Thunder strike for tankers/scrappers
Only Blaster and Dominator Thunder Strikes do KB (and Defender one from their EPP)
Scrapper, Tanker, Brute, Stalker and MM (from their PPP) Thunder Strikes do KD.
Holy crap, I never knew that. I just assumed they were the same as the blaster version. This changes my view of electric melee a bit.
Having Vengeance and Fallout slotted for recharge means never having to say you're sorry.
The description says foes near the target will be knocked down, but with my blaster's thunder strike, foes near the target are knocked back.
I just want to verify it is knock down and not knock back, or I will probably skip that power.
