X-factor is broke on sooo many levels. the dmg and the speed just make your character a bastard, but where it gets fucked up is turning anything into a free punish that when combined with the damage is a free kill. if i have x-factor and they dont i will often bait a block string and x-factor for a free kill rather than activate and charge in. It also heals you and your team and has hidden character specific buffs.Then there's the damage reset and ability to extend combos and creating assholish 50/50s (EX: Akuma block string > X-factor > low or f.M mix up = DIRTY SEX COMBO SET UP)
Really they need to nerf the whole damage of the game, there is WAY too much reward for sneaking a jab in on someone. I originally felt meter would limit the explosive combos...but then we learned you can do all your meter building in huge no-meter combos and still do a HUGE chunk of damage. Then they need to take away the ability to get a free punish off of anything with X-factor. If they did that it wouldn't be an issue.
Really the game plays great but there's too much reward in that game and then DHC glitch just sends it over the top.
