Ice APP or Mace PPP?

[biostem]

I've been playing a grav/marine 'troller recently, and have been having a lot of fun with them.  I'm just about at the point where I'm going to need to decide which APP or PPP to go with.  I want a defense shield, but beyond that, I can pretty much make anything work with the character theme-wise.  I've narrowed it down to ice mastery or mace mastery.  The biggest determining factor for me is whether I want/need the extra bit or survivability hibernate has to offer vs the general, (at least IMO), coolness factor of being able to have the mace as a costume option and then to also summon an extra minion, (tarantula).  I had also briefly considered earth mastery, but I think the FX may be a bit too intrusive...

Scorpion Shield is better than Frozen Armor but I prefer Ice Storm over Disruptor Blast for additional AoE damage.

Could also depend on what you want the build to do. If you're trying or want to try to solo AVs and such, then Mace Mastery is the optimal choice for Poisonous Ray which you can proc out and slot an Achilles' proc for additional -res. While Disruptor Blast doesn't provide as much damage as Ice Storm, it does allow slotting of the FF +rech proc, so some things to consider on what you want to do with your controller.

 

Edit: I would also add that survivability shouldn't be a big concern for you since you'll have PotD from marine which helps a lot in that department along with all the other goodies like Toroidal Bubble, and Barrier Reef.

I ended up going with Mace Mastery.  Took the shield and disruptor blast, (the one that debuffs DR and DEF).  I may take the spider pet as a later pick, if my build allows...  Thanks for all your input!
