Instead, why not buy a chosen squad? The champ in there is only 28 points, and they bring you a much needed way to get close and wreck an opponents back table huggers.I agree with the DP thing, swap for reg DP with WT much better than MofK! Also you're champs all have PF's that makes your GD alot more expensive when he arrives! Just a thought might be worth taking PF out of the melta squad!
The only other concern is the termies! if you deep strike them near heavy support choices wont they just get annilhated? Wouldn't a small termicide squad be better suited for this role??
