Hmm. Well I can't exactly remember the amount of bonus renown for sc wins. I think it was something like 1600 in t4??? I should of course scale with tiers, so maybe 400 for a t1 win? I also think the XP you get from a win should be very good, because that way people can level up through pvp, and never feel like they have to grind mobs if they don't want to.
As far as capping BOs go, I don't think that should give any renown. IMO, renown should be gotten from a total zone cap as opposed to capping a single BO. Xp is whatever though, as one can already farm xp by questing, grinding ect.
Ok now the big one.. Public quest rewards... as a longtime player of war, one of my problems with PQs was that as the game introduced better and more easily accessible gear, the rewards for PQ were nearly always inferior to the options you could buy from a merchant, and eventually people had little reasons to participate in a PQ. In a nutshell max, what I would really like to see for PQ rewards is a good item/piece of equipment worth my lvl/the difficulty of the PQ. I know there are those old school pve sets you can get for t2 and t3(I remember ruin was one of the sets) so maybe things like that. And purple equipment pieces are nice

For how many PQs there are in this game(some of them being really cool) It would be a shame to sweep them under the carpet as was done when the game was live. I think it would be a very good call to dust them off and give people a reason to do PQs.
