I'm glad you decided to add constructive reasons and explain why you feel this way. Great post here kid, the devs will just skip right over this and not even think twice.
edit - I like the changes btw, it adds more skill to the game.
From another thread:
The changes for DPS sorcs are bad. Very bad.
Most DPS sorcs rely on insta-cast spells or channeled spells that have no cooldown. If you want to play a DPS with big activation times, there are other classes that have it and can deal bigger hits. We exchange big hits for extreme mobility and lots of utility (pulls, stuns, roots, mez, force speed, etc) with the occassional heal spell. So now if I spec high in lightning I can be un-interrupted for 10 seconds.....I'm never interrupted anyway as everything is instant cast or channeled with no cooldown....useless for Hybrid/Madness, only useful for those rare folks who spec very high in lightning (why?).
Look at the changes. We get force speed to 20 seconds....I already spec for the 20-second force speed. No mention if that goes to 10 seconds now. This would be a modest boost if it does; if not then it's meh, nothing.
We got our stun reduced to 10 meters from 30 meters. Since some players have 30m range to hit you, sometimes a stun was what was needed. Now they can still hit you from 30m range, but you can't stun them. Clearly this lowers our survivability.
We got overload reduced to frontal 120-degree arc instead of 360-degree arc. This is a pretty big nerf, as anyone chasing you can still chase you, or you have to turn and face them, which just allows them to hit you a few more times than they would have if you had a 360-degree knockback + root. If they are surrounding you, you're now doomed.
In exchange, we get a modest insta-cast heal every 30 seconds...which probably activates your global cooldown. No word yet on what "modest" is, but ranked warzone groups don't want a dps that has a good heal ability...anything less than 5k is useless; I suspect it will remain well short of that.
Without a major increase in damage, the class went from being considered mildly underpowered to now a joke. This pretty much forces sorcs to go healing; my operative healer already heals for 500-700k per warzone, so not sure why I should play a sorc at all then.
