That may be true, but bakemono's ability to search(sisters, lv 3 hitagi, gate triggers) waiting room to replace their units easily can push each turn for soul damage. Miki's encore's ability is dangerous in the late game because both players will start to minimize their damage output, not to mention if it would really suck if you clocked a much needed climax. I really like the lv 0 stuff, (mami is great to start with)
IM@S2's Lv 1 game is very weak, simply because imas have to burn stock early game to match up to even with Yukiho support. BK Maniac is a great card as well, which also fuel's 0 haruka's amazing support ability. Not to mention it's extremely stock dependent (Haruka's change, Kotori's startup, etc). Lv 2 Yayoi is a really good support, but I've been able to get her out once, (Other times she either gets put in as clock damage or in my stock.) I understand that people may say it takes some more thought into the moves, but the trade-off for some effects just aren't worth it. 2 TDs combined will probably make it much better(for another set of yayois and harukas)
Just my 2 cent.
