Wouldn't recommend unless you don't have the proper gear set. Only have 10 points in Spirited but with all my gear it's at rank 26. Quickening breeze is good because of both the active and passive. 1k dodge helps alot when you have a pym's shrinking to help regain spirit. Plus the +~30% attack speed increase is really noticeable when spamming ball lightning. To each their own though!

i dont know how u managed to put 10 points in spirited i only have 1 in it without boosts from gear

did you do the skill point quests in each difficulty. you get an extra 12 points if you do all of them.

This is discouraged because Quickening breeze supplies the wind power to trigger extra synergy procs from her other abilities.

no I probs did not, but anyways I used a retcon and maxed quickening

Yeah it's not hard to farm Eternity Splinters for new heroes. I bought some G to get Taskmaster because I just really wanted him.

It does get a little daunting at first though. If it were not for the first free pack of splinters for dropping doom I think I may have quit right then and there. Once you establish a roster of heroes it helps the game play quite a bit.
