Entropic Aura - not set up for the +recharge buff
Divine Avalanche/Parry - not set up to provide +defense buff
[Also not sure if the Scrapper and Brute values for the +rech buff in Entropic are supposed to be the same... but my brute (in game) hits +45% recharge with max targets; Scrapper is only listed at 24%.]
Re Entropic Aura it looks like it's applying the -Rech to the player. Activating it 0 targets makes the recharge longer than base, it takes 3 targets to almost counter it (-16% vs +15.5%). Also, I only get the slider to set the number of targets on the Scrapper version, doesn't show up on the Brute.
Edit: forgot to say, the +3.5% Rech field isn't updating as you increase the targets (it shows the correct amount on mouseover however).
