Oh yea I missed that since I only browse swordsman sub-forum and news section. SP seems like the biggest issue of new Cata.
EW: No one fully tested EW yet (KD on + acrobat mount) + high end spears with high trans + crit build because all the damage now comes from the weapon, skills only act as multiplier. So it would be more accurate if someone with OP gears will use that on end game scenario (meta). Right now my EW deals around 200k, if the patch comes here it would deal 4x at minimum if not 7x of my current 200k. Im even an evasion-con build, if I focused on crit build the damage will soar.
SP drain is nasty though like Nekorin has said. Steed charge seems needed timing maybe only 1 sec window in order to use twice. Maybe we should avoid charging steed charge and use it right away on the 2nd charge for it to work consistently so turning around 90 degree will waste the charge.
I like the change, SP drain wont hurt me that much as long it gives damage boost where cataphract seriously lacking(stuck at r6 with little to no buffs). I know some option to mitigate this SP drain con. Cant wait to test all the builds myself when it gets here.
