Really seems like you are "back in my day"ing. People always do this when they love something and don't want it to change. No, I'm just point out the flaws that people don't want to admit exist in WotC's way of doing things. Because apparently only GW is able to do anything wrong. Ever.
Just like a great band can't keep releasing the same album, MTG couldn't keep releasing the same editions. No long running game can, but MTG invalidates older decks by taking them from being played at all when new editions roll out (outside of casual play or one specific tournament type that has a banned/restricted list that is basically a small book). There is very little carry over (mana and some basic cards) so whole decks can be invalidated with no way to continue to play specific kinds of themes. It's like a band that switches genres every album.
It had to change to keep progressing and is the only CTCG I know of which after 15+ years is still increasing in popularity. I don't play anymore for the same reasons you don't, but had they kept the game the same, no one would be playing anymore because it would be OOP. I'm not saying they shouldn't change, I'm saying they suck at long term balance. When it comes to balance GW actually does a better job overall, and has erratta'd things to fit editions better when the fans asked for it. WotC just bans/restricts things instead.
Also Draigowing? Have yet to see people winning major tournies with that one... last time I tried a Necron tank IDed an entire squad with a single blast template, lol balance. Not to mention a decent deck of MTG doesn't cost as much as even a Draigowing let alone the thousands people drop on GW models. And just wait, come June they will cost even more... GW models, still good between codex changes, MtG, only good if they reprinted your cards into the new edition. MtG is a game made of thin sheets of laminated cardstock, GW models are made of resin, plastic or metal. No comparison for pricing works there. But I stand by that the GW models are able to be used longer thus meaning you get more for your money overall. More expensive, sure, but they're still valid for a lot longer.
And why are you comparing a Miniwargame and a PnP RPG and CTCG? Apples and Oranges. It's only a matter of time before WoTC releases a wargame of their own and probably take a huge bite out of GW's sales. There is no minature wargame to compare to so all I've got is the existing trends that they have with their games. And because the trends WotC follow are the same with pretty much all of their games it's what I've been making my baseline comparison with. WotC produces lots of product for something, damns the balance, and make money because people will scramble to buy it just to keep up with the power creep that comes with every new set of cards, and every new book. It's actually worse than GW's in a lot of ways because it enforces mandatory bandwagonning. Sure you can play for fun (and in D&D ignoring anything not in the core rules is usually for the best anyways these days) but you have to jump onto the next big thing just to keep up. Oh, and say you liked your (say) Wood Elf deck? Too bad it's no longer tournament legal outside of one specific game type! It'd be like an army being squatted every new edition that came out only to eventually get a partial replacement sometime before the next edition came out. And it's more WotC would just buy out someone else and update that over and over again pushing it away from being anything recognizable and more into being something like something else so they can try to make money from a new demographic (the move of D&D 4th towards being more like a tabletop version of WoW is an example of that). GW produces new specialist games from time to time, but I can't think of anything in the last 10 years that WotC is responsible for producing that was wholly original to them. I may be wrong, but I can't think of anything.
Not sure where you are from but GW doesn't do a better job here state side. They dropped tourney support, closed most of their retail locations and enbargoed sales from overseas. Now if I want to buy models I either drive 2 hours to the GW store or order on GW dot com. Any other retailers can't undercut the price and shipping takes long than ordering direct. Thanks GW. I'm in New York state so I get a massive tax markup on everything I buy (the big paint set had a $45USD mark up from taxes alone). The loss of the tournament that was being accused of imbalanced and poorly run isn't something wrong (infact people should be HAPPY that it went away after the amount of negative response I saw last year), GW still runs tournaments in their own stores and has now a budget for supply prize support to FLGS now who keeps their products in stock (an improvement). The embargo was silly but there was likely a legitimate legal reason for why they did this. And if you think the loss of GW's is bad now (you can thank a bad economy meaning they can't afford to keep every single store open which means the stores that don't pull in enough money HAVE to close or GW would be taking big penalties finacially which would hurt us worse) IF WotC bought out GW (somehow) I don't think ANY GWs would still be open because it'd save them money since they can just sell their stuff in Big Box Stores and FLGS instead of needing to pay more employees so everyone would lose their GWs.
