... At double post.
But you should be able to find an okay team, but a lot of teams i find now are GS teams :/ And if i were you i'd get 70 prayer. But if you want a team for sure you can always try to tank. I tank quite often with 80 def and actually lower stats than you suprisingly and last quite awhile, if you have two tanks on a team then you can go for a really dang long time. At the moment my perm team we have 3 tanks, and usually average eh, 1-2m or so on a completely shit day. Learning to tank is worth it and its something you should look at.
EDIT: By the way, i'm talking about a bandos team.
