its nothing wrong with going for TU's. i just want to show why its less reliable on that kind of rush:
(...) waiting for a TU won't hurt you that much, and it will enable you to set an impressive 24 dmg on the table in one turn (plus 48 the next turn), just in case everything else goes wrong.
(...)
its a rush - waiting is always not optimal in a rush
also the deja-vu's are squishes, any cc will hurt them. if you have a adren + monumentum combo you usually dont want to wait (and get it destroyed) for a TU.
1 deja + epidephrine + monumentum = 12 dmg -> using abillity = 24 dmg -> TU (allready used ability) deja-vu = 36 dmg
you get the 48 dmg combo if you can TU in the same round,
before you use the ability:
1 combo = 12 dmg -> TU = 24 dmg -> 2x deja-vu = 48dmg
also 1 monumentum 1 deja 1 epidephrine 1 TU and all the quanta to boost that combo is tricky to draw.
long story, short sense: TU can be faster, but gives you more "bad" draws.
