The problem is, is that now that DEF and RES are a percentile number, the bigger the numbers are, the larger decreases they get, a 500 cap EI against somebody with 40 defense would essentially be 300 damage, and that's not counting when people are running other DRs into the equation, 300 -30%(wraithguard) -10%(ogata waraji) -10%(one vs one) for example would bring that down to..170.1 damage, and while not many damage instances get higher than that, it ends up being a real significant chunk of what it could be.

I guess the real problem here is that big damage numbers don't feel like big damage numbers, stuff like Excel Weaponry, Charge mind and EI, very notorious burst tools, all just seem lack luster now.

However I can see a cap increase "fixing" one of the problems raised in the OP, where it just doesn't do as much damage as other weapons atm, so yes, that'd solve one of the problems with the skill itself, if you'd like I'll raise a separate thread on the burst skills mentioned above.
