@HiddenTrap CWW has revealed on the discord that there will be many different round types, chain lightning and pierce included. I'm not sure on the workings of them of course, but don't worry... OE4 will be epic.
I think it would be pretty neat to add events to the pvp, that would modify gameplay. For example, perhaps a holiday event that doubles the effect of tech. Limited time events could be really fun, so consider it pls.
