But what about radial blind and super jump? Those abilities are completely useless.
No they aren't.
Every ability is worth getting somehow. Use them situationally.
They're not all always good, they're all worth the 1 point though.
Super jump = good for high jumps + future melee slamdowns + fun.
Radial Blind = everyone can't see.
wow look 4 uses for those.
Or teleport for Ash.
Use on allies to get to safety/revive faster.
use on enemies to gain/lose altitude/get into melee range.
all skills are worth using.
