Consider it this way. Currently, the metagame and each beys performance is on a knife edge. If it's not quite right, it's going to lose most of the time, if it is, it'll win most of the time. That's why a lot of combos currently require a lot of tweaking and other specifications to beat the maximum number of opponents. Take (No MF) Gravity perseus (ATK) CH120XF (NORMAL mode). Unless it's in normal mode, it doesn't outspin basaltbd145 easily, but if you use a different wheel, you won't do as well against 230 combos. (I would do testing to show this, but I don't have time right now). It's all about getting the right balance.
This is why R2F and LRF is such a difference. You really need that little extra speed.
This is all due to the extreme levels of performance of current combos, BasaltBD145 is pretty much the epitome of this, in my opinion. It often holds on by JUST enough to stay in. I'm not sure if this is why I find mine much harder to beat than others seem to (I use a hasbro Aquario, and purchase a new CS regularly so I always have a good one for it). Anyway, you need that extra power to push it over the edge. If you have that power, you'll do well, but if you don't, it's gonna go to the edge, and no further.
This results in a metagame that requires me sitting down for hours at a time trying to get the balance right for new parts. It also means that differences in launching ability, part condition, and what not affect results much more heavily.
I hope that's simple enough. A quick summary would be that we have a metagame of extremes, where the smallest change can be the difference between winning and losing. We have hit such extremes that every tiny factor affects the outcome, especially in ability to outspin and KO opponents.
So, uh, yeah. That's what I think, anyway.
