As far as the whole "reflexes" thing and practicing pvp. (From the op)
Getting the reflexes to be good in snubs isn't hard, getting the reflexes and intilect to be good at video games isn't hard at all.
It took me 1 week to get the skill and confidence in snubs to raid and kill effectively. It's the same thing with caps. The part that seperates person a with good reflexes and timing from person b with good reflexes and perfect timing is that they have used those reflexes more/conditioned more and know every little trick there is to beat your opponent. That's what I think the case is in a balanced duel between 2 people who are smart. Noticed I didn't say skilled, with most group fighting cases it's really just common logic. With caps its placement. With snubs (from my experience) it's timing.
Getting good at this game really isn't that hard. It's just a matter of patience.
Snubs are harder to perfect than caps, caps fighting in group fighting is all placement. Snubs in both cases is timing timing is harder to get down than placement.
The issue is that getting good with snubs isn't as rewarding since the bulk of the server uses caps, and it's easy too crash a snub fight with caps, you may not be damaging the snubs; but having a cap on one side of a snub fight puts way more pressure on the other team than you think. Hence my original proposal.
Yber was right, you can't change one without demolishing the other. This situation is basically a stalemate.
