Hey dude, hope you have fun with your new blaster!
Blizzard is now alot of fun in PvE - the sheer size of it's area is awesome, and with powerboost, aim and build up I've found I can usually get away without using Icestorm.
When it comes to ancillary pools, for PvE, I'd recommend elec or fire. Having two fast holds is really nice for soloing. RotP is pretty awesome if you die and EMP ca be a handy panic button,, although it's recharge is huge. However, Elec defeintly has the better shield, seeing as energy damage is just so common. I currently have elec, but am probably about to resepc into Ice for PvP purposes as detailed in the thread currently just below yours 
Boost range certainly has it's uses to help you out range stuffl but will be less useful with leaping. Its awesome with fly as your out of melee range, and boost range allows you to sometimes stay out of range of all damage, whilst still dishing it out. However, this certainly isn't the case against every foe 
Hope some of that helped a little dude!
1) it's worth getting now thats its buffable with aim and build up.
2) for pvp you want ice or force mastery. i'd go with ice its a bit more fun and hibernate and snow storm is great.
3) boost range is very good it allows you to outrange the other blasters. It's not neccesary in pve in my opinion. it's skippable in pvp as well but it's a nice asset.
blizzard is a great power, Boost range is always good, and I'd go for elec or fire epic for 3rd hold
Blizzard is great, it permit you to nuke standing away from mobs (you dont have to go close as for Nova or Inferno), more accuracy bonus than oter nukes, plus, it has a good control that helps team a lot.
Being an Ice blaster, i dont think you need other hold powers.. you can already have 2, and even if you skip bitter freeze ray (i did) you're freeze ray is amazing cause very quickly recharge, expecially with hasten... definitvely the best hold power in blaster sets. so i would suggest ice or force
hi,
recently rolled an ice/en blaster. i plan on being single target ranged attacker with blapping as a backup. taking leaping and fitness pools. concentrateing on pve with pvpable build.
i've got a few questions and any advice from people with ice/* or */en experience is welcomed.
1) is it worth getting blizzard (especially if combined with the other rain power?)
2) what would you recommend as an ancillary pool - considering force mastery at the moment
3) is boost range useful without a snipe?
any builds would be helpful as well. thanks
