Can somebody please update this thread? lorebook.lotro.com/wiki/Warden:_Tanking_Guide?
This is what I relied on when I was starting out and a lot of it is no longer valid.
I met a great warden that taught me to switch stances depending on the situation. I now do it regularly and it helps a lot when soloing. In groups, I stick with determination unless everything is under control in which case I will switch to recklessness and do Power Attack, Onslaught then Wall of Steel for extra damage then switch back to determination.
I did the rift at level 56 with 10 level 85s. There was a level 58 warden and lots of level 85 guards there and only one hunter. In this case, I thought it prudent to switch to assailment and did Offensive Strike, Combination Strike, and Boars Rush combo. It gives extra damage in this stance.
Lastly, I prefer to do color codes to memorize the combos i.e RGY for Power Attack. Its just my preference.
