As I plan to be a crafter I look forward to gathering supplies in Cyrodiil, and the dangers that brings, the most.
Looking forward to all the others aspects of PVP as well of course
I would prefer siege defense, if the siege itself is overall well balanced. Other than that I am not much of a PVPer or competitive player.
I generally avoid duel type games, free for all and basic non objective killing spree for scores type gameplay. Team based games with different tasks and objectives are okay. More tactical and moderate paced games are rather enjoyable, mindless zerging is not made for me.
If healing player's counts as defending resource's, yeah.
Edit: thought i'd add i realize you wrote recourse, and not resource. However in a defensive playstyle, it is all relative, so i'll say it that way regardless.
All the above, I will do what the situation calls for, I never really have a plan just go with the flow and where the action is..
