Skill Changes -

Light Strike: Defense/EVA up, attack/crit down, lasts 2 minutes (1.5 min cooldown)
Flurry: Defense/EVA down, attack/crit up, lasts 2 minutes (1.5 min cooldown)

This is to incorporate the "stances" idea that they seemed to have abandoned. If you tank, you will use Light Strike, if you DD, you will use Flurry.
by putting tp moves on a long cool down you have probably negated any dps benefit these skills have. Your tp getting moves are huge for dps in terms of extra dmg and tp building, it also allows you to make better use of skills that need specific conditions, like comrade in arms, murderous intent, dicerning eye, etc. Basically you cant increase the cool down of these skills without drastically reducing dps and usability of various skills.

But yeah, most of your post will probably need a rework when you see the new balance stuff. Even though your overall ideas may still hold up, the implementation and critiques could be very different.
