Best is to use kaioken against all
In pvp and pve aswell or use both if one is in CD

And I dont have problem with my kaioken it do lot more damage then ssj

Unless in tw they made kaioken to drain a lot

TW DBO has the exact same meta-game as KR now please do not say that there a stat difference because there isn't.

Every version is the same now ~~

In PVE I used kaio x2 because it increased crit by about 8. If this isn't the same then I'd have to go with ssj as it only drains EP and is safer when farming a lot of mobs at the same time. Kaio's only advantage was able to crit more/higher so faster mob killing, specially if paired with a dende.

*not meant to hijack* now that kaioken is 'fixed' next should be nameks 100% anti crit :P?

Either sticking close to the tank or the healer should solve problems of the healer having to focus some heals on you since dendes normally have at least one aoe heal that they will either be using on them self or on the tank. Hence you should be able to get heals and not distract the healer too much, although this doesn't always happen.

Also I don't normally go x10 or even x5 in party pve, I usually go x2 or x3 so this might not work at higher lvs of kok.

I prefer ssj for both , only have to focus on ep then , with or without a healer I just find it more useful , autoattacking is strong , and i prefer in pvp . I one shotted a 26klp namek 2 days ago without kaioken , he obviously wasn't wearing anti crit , but even with anti crit effects kaioken would then be equal to ssj

i didnt said it difference try to read what i said
i said maybe it different
