Sorry, I should have posted this feedback sooner. Good summary AmericanJudkins.
The battle at the beginning of Heroes' Ascent is pretty much the same group as there was when it was at Tombs, just the terrain has changed. However, as was stated above, we just didn't seem to have the spike damage to take out the ghosts.
I think IWAY should be a pretty good one to try. From what I've heard it requires a lot less coordination and is a common PuG build. I don't know too much, but I believe this build uses about 5 W/R's. "I Will Avenge You!" gives regeneration (per dead ally) and faster attack speed. They use longbows to send pets in ahead. Hopefully an opponent will kill 1 or more of the pets to trigger IWAY, then the warriors run in, semi-invincible from IWAY regen. The team is usually filled out by monk(s) and necro(s) and sometimes a trapper.
Ranger spike would be another OK one for us to try because of all the rangers in the guild. The biggest trouble I see is that it would still require coordination to make the spike hit in sychronization. Not to say this is impossible, but I like the idea of a less communication intense build until we get our footing.
Another build that I (and one2dredd) would like to try is the ViM Trapper build. This is one we first saw in the Zaishen Challenge. Although traps are easy to interrupt, a group of 4-6 trappers all going at almost the same time would be difficult to interrupt. The idea of the build is that once the traps go off and cause conditions on the enemy, the R/W can use the warrior elite "Victory is Mine!". This shout provides healing AND energy for EACH condition in the area. With 1 trap causing bleeding and crippled, one causing blinded and the third causing burning, hopefully on multiple enemies, this is a VERY powerful recharge. If we round out the group with a couple monks for short term healing until the traps hit we should do well. We might even be able to make it look like we are a spike build to draw warriors in.
Any comments or suggestions? I will try to post some more detail on these builds later. I will need to look into IWAY and ranger spike a little closer before posting more detail than this.
