Just remember that PVE builds PVP and PVP doesnt build PVE, so it may help to focus on some PVE elements early on. In addition, if you wish to keep leveling late game and save vit at the same time for the UBP event setting up a PVE based team might be better early on.
Take vanguard killer, always start pve, then tune you're reatsu, it will help you take the lead when you go on to gold characters its the best way to dominate you're server. First get pve characters then pvp
