Help with Earth/Ice troller....

First off welcome to controllers!

I havent played my Earth controller in some time so unless something significantly has changed everything you mentioned with the exception of Stone Cages (and possibly VG) will only have a chance to proc upon casting and every ten seconds after that (until the duration expires). IMO out of the powers that proc every 10 seconds I would say Sleet and Earth Quake are the only two powers worth procing mainly because they can take multiple procs. With a greater number of procs you stand a better chance that a proc goes off. Snow Storm and Quicksand are not worth it IMO but its been some time since I have tested it.

I personally use procs in Freezing Rain (and pleased with the results) I would say its a go for using them in Sleet. My understanding is that Sleet is bugged, so it may affect how the procs behave (most likely not). I cant test Sleet for you as I just deleted my Cold/Sonic defender, perhaps another /Cold controller can give you better advice here.

There was recent thread about VG a few pages back where one of the posters recommended procing VG. Looking at the power in Mids it looks like a great opportunity to use multiple procs including the Lockdown proc.

If you spam Stone Cages in most fights I would proc it; if you dont, don't bother.

Arctic Fog may get fixed in the future so I would recommend going with Ice or Stone so you can stack for S/L defense. If defense isn't your bag go with Fire to add some offense, Psi helps mitigate status effects, Power for power boost and conserve power. I think Local Man's Ill/Rad guide has a good break down on the controller epics

GL with your controller!

No problem.

Seriously go look at Local_Man's guide where he breaks down the in's and out's of each APP (Epic) you may find something else you are looking for.

Good Luck
