Try a quick google?
Urgh, just realised its 20 wvw points for 1, yes 1, supply carry increase. I thougt it would be at least staggered in 2's to give you 20 but no 1's for 15
It's a time sink rather than decent rewards sadly
Still it gives me something for my time spent
Only rank 5 mind
Somehow ended up in a really good wvw guild on seafarers. Royals (or something like that) I got myself an invite after leading a small 5 man team if royals who I randomly invited and we went round the whole map and took every supply camp as five men
they got took back but caused a lot of disruption. What tipped it my favour was my heroic last stand. We took the ogre place and then a huge Deso Zerg came rolling toward us, they ran and I faced a huge Zerg solo
I shock waved the front rank backward into a pack of ogres, stealth end then jumped a half dead Ele I managed to take out before they stomped me flat
insta invite after my heroics
