Your are very right that we dont have a minimum range. I have tried this many times and it doesnt seem to push them to retreat or back up. Also overload only pushes them about 8m away. They are rooted and cant move for a bit but they aren't stunned unfortunately, meaning they can still attack, 8m is just not enough. Other classes can push me further and some can also stun me in the process. Force storm doesn't do much damage unless you cast it on a group from what I have witnessed so far. I wouldn't mind seeing force storm at least slow a target down, then i might just forget about more melee damage.
What others have mentioned:
1. Toilet Paper armor - I remember ack in the old days of D&D where a magic user wasnt allowed to cast if they wore something heavier than a light robe. So im fine with that.
2. We do have one ability that breaks stuns but unfortunately in takes forever to cooldown. So that can be fixed too IMO.
Not asking for a god button or the famous up, down, up down, left, right, left, right, A, B, Select, Start. A few tweaks here and there and Sorcs are balanced against other classes without being over powering.
