First of all, the way I read the letter I don't think Joel is leaving.
I am afraid Joel is pushed more into the manager-side of his job. Poor Joel.
Second:
When i read about using different weapons coming available for classes, I can't but wonder about how this will connect to T5 gear. (Which i don't have)
Some of the buffs will completly useless for classes.
And for the combo's to do with them: I would love to see the level 2 Sweep and level 4 Slam back in a higher version.
It would be nice to have a knockback on my HoX.
