Oh my comment on the style of play wasn't directed at you specifically. Its just a general observation on the way Skaven tend to play, and on what I've found makes them deceptively hard to be good with. Easy peak, and then a massive plateau because they can't overcome the "keep anything other than GR alive and developed".

Yeah, the effect Megrim is describing is not necessarily the result of a specific playstyle -- the GRs tend to become overdevelopped naturally, as a simple combination of playing to win games and everyone else dying. Though you might have some early opportunities to get TDs with your Stormverin, after a certain point they have far more important things to do; and unlike with otherwise-similar elf teams, feeding SPPs to your agi-3 linerats is extremely difficult.
