Why "Might" instead of "Spirited Roar"? Because "Spirited Roar" increases your strength but it decreases your defense really much while "Might" only increases your strength. If you wish to you could max "Spirited Roar" instead of "Might" but you would need a good armor to cover the side effects.
Kaioken is not needed since it takes a lot of EP & LP per second so it's kinda useless for PVP. You could use Kaioken against bosses and mobs and so on if you have a healer on your side or if you are buffed (Ultimate Majin buffs...). You have 2 stuns "Kidney Shot" & "Quick Attack". Most people use "Quick Attack" 1st and then do some damage with "Wolf Fang Fist"
or "Sword Slash" and then they use "Kidney Shot" to stun their target again and some more damage usually with "Multiple Sword Slash". The skill "Scintillation" is really useful for PVP if maxed. You can use it from the begining against humans & namekians (Shadow Knights) & wonder/Karma majins too because they have stuns. Use Block while having this stun and your chance for a dodge/block is guaranteed. Which will give you advantage.
Also you can use RP points to increase the duration of your stuns or cooldown,increase the damage of your skills & reduce EP cost of your skills (which is not used often...the "reduce EP cost of your skills").
