After playing since the first day - I got to where just rolling a character up was boring, so I would either make a concept or study all the powers and then design a playstyle that often was beyond what you were supposed to do or was done in a completely different manner.
My first character was a blaster and my last alt was a blaster. I loved the blaster playstyle and so I designed one specifically based on using range as my best defense. I chose Sonic/Ice/Ice as the best ranged choice.

Shriek - Ranged, Minor DMG(Smash/Energy), Foe -Res
Scream - Ranged, Moderate DoT(Smash/Energy), Foe -Res
Howl - Ranged (Cone), Medium DMG(Smash/Energy), Foe -Res(All)
Shockwave - Ranged (Cone), Minor DMG(Smash/Energy), Foe Knockback, -Res(All)
Shout - Ranged, Heavy DMG(Smash/Energy), Foe -Res(All)
Amplify - Self +To-Hit, +DMG
Siren's Song - Ranged (Cone), Minor DMG(Energy), Foe Sleep
Dreadful Wail - PBAoE, Extreme DMG(Smash/Energy), Foe Disorient, -Res(All), Self -Recovery

Chilling Embrace - Toggle: PBAoE, Foe -Recharge, -SPD, -DMG

Ice Patch - Location (PBAoE), Foe Knockdown
Shiver - Ranged (Cone), Foe -Recharge, -SPD

Snow Storm - Toggle: Ranged (Targeted AoE), Foe -Recharge, -SPD

Frozen Armor - Toggle: Self +Res(Cold), +DEF(Smash, Lethal)
Hoarfrost - Self Heal, +Max Health, +Res(Toxic)
Looking through the powers I found a gameplay style that was based completely on slowing the enemy or repulsing them from me so that I could destroy them at range. I had 3 sleeps, one mass knockback/knockdown (when slotted) that when used when they hit Ice Patch would even send bosses flying or flopping - I had multiple slows -Damage toggle if they close, a self heal, Armor and multiple holds. I could sleep nearly anything in the game and then tear them apart at will. In team the stacked sleeps still worked and the enemy slowed to a crawl and with -resistance in every Sonic attack and -slow with every ice attack was the safest and most powerful blaster I ever had.
I was able to tank Lord Recluse for over 30 seconds when the tank died using my armor and the -damage from Chilling Embrace and my self heal. After we got the tank on his feet I stayed with him debuffing Lord Recluse's damage and we had no further trouble. The rest of the team was amazed to see me surviving when the tank had the defense catastrophic failure and died in seconds and yet there I was still fighting and slowing recluse.
The only problem with Sonic was the god awful sounds effects. Mix a Sonic Blaster in with a Demon MM and everyone had a headache.
