I agree that Elite Engine is not worth using in it's current state but I don't think it can go back to how it was either.
Exponential scaling with multipliers aside (they're not so easy to obtain these days anyway), the issue I see is mostly how you can just keep yourself sitting on Lv3.
For instance, let's say I reach Lv3 and hit you, that'd be a roughly doubled damage hit. Now I'm Lv2. Instead of striking again for 70%, I could instead throw in non-excel skills for the other actions. Then, I could easily return to LV3 thanks to the Conversion Gloves + Shock Collar combo and basically keep doing that each round.
In a vacuum, it doesn't seem like a big deal but because there are ways to build up charges that aren't costly, it can become a problem.
