Hindering shot is useless without a huge accuracy boost. As an MA your ballistic defence is fine but your accuracy is bollocks.try even hitting an MKT with it.
Hindering Shot misses way more than it hits. I actual rarely use it because of that (fair enough the odd time it hits and you can get them in il.) Theres been sometimes I'v been at mara and missed hittin a lowbie, not once but as much as 8 times (that time i actually just gave up lol)
Ki Burst is really crappy. I only use it when we have more numbers, hit prowess and that and you're lucky to hit what 150 dmg? 70 IS for a really low dmg move and like a 30% chance to enrage (which rarely works lol saw countless people roll out after i'v hit them with it.)
So yeah I'd like to see Ki Burst to something a bit more useful and lower IS.
