I like having choices when I played AST.
Balance may be good for more DPS, but the of variety and using different and fun cards was....well...fun...
I like when I got balance sometimes for "Wee! DPS GO! ", I like getting Bole for AoE or tank busters, I like having Ewer to help me or my co-heals, so and so forth.
Like a roulette for me and using different cards for different things...
It was just fun to mess around with the card system, now look. -Sigh-
