Last night Melf told me about a neat little trick he discovered on the forums for gaining Renown in WAR scenarios extremely quickly. All you have to do is change teams in the scenario so that you are alone or with the mates you want, and you will gain a stack more renown (the less in your team the better). The trick sounded very simple, so naturally Melf and I tried it for ourselves. Sure enough... it worked...
I used my Warrior Priest (Starmantle) and Melf used his Iron Breaker (Drogan) in the Troll Crossing scenario. We created our own little team in slot 10 and played as we normally do.
To change teams in a scenario you right click your character portrait and select 'Leave scenario team'. There will then be an option to join any other team you like. Just click the 'join' link at the bottom of a team slot in the team window.
Here are the results of the first match. Yup, Starmantle and Drogan top scored for Renown. Not bad for rank 17 and 18. The XP gained was nice as well:
Similar results in the second match (click images to enlarge):
This neat neat little trick isn't an exploit. The reason you get more renown than everyone else is that you don't split it with your team mates. In other words, you don't have slackers sapping the rewards for your hard work. The other advantage is that you always get the rewards from corpse looting (he he, no need to roll). The downside is that you miss out on all the buffs associated with being in a group.
Although it is great to finally get the renown I have worked for, I really hope Mythic fix this problem because it promotes solo play in scenarios, which can only lead to disaster.
