That just made melta bombs on squad sergeants more important.
Blood Angels do it nice with meltaguns in a Drop Pod. It's one of the only 'competitive' things the Codex offers: 135 points for 4x melta shots provided you can disembark with your sergeant within 3" for the shorter range of inferno pistols. I like to spread them out against two armour facings on a Knight; it rarely kills them but it puts the hurt on pretty reliably.Point of order, if you want to gib an Imperial Knight, the Sororitas still have you covered.
Thanks to the above combined with the typical amount of melta/lascannons in my army I've never had an issue but maybe that's because I play marines, eh? I mean...they're the most ill-equipped marines, but they're still marines.It's 2016 and people still think that Imperial Knights are hard to kill?
