I just thought of this while looking at the Indy war sign up on profile page If you are looking for clan wars during the week you can select a merc option for the wars you are available for and you will be posted in merc marketplace Each merc can post a small synopsis of stats build tracking or lead exp and clans can contact them directly through the marketplace Maybe they can be sorted by cs as war clans are usually looking for certain sized mercs to fit their roster This could be used instead of or in addition to the cluster-mess that is mercing in WC Thought?
Seems like you could make a thread for this exact purpose. If it gets enough people's attention. Then you can merc on the thread and people's clans that need someone can check most recent posts n grab em for upcoming war. No need to make entirely separate marketplace.
I have lots of tracking and little WC experience however I do have many friends experienced in both aspects
To add on.. Owner/admins could make good or bad comments such as "inactive" or "*insert positive thing*" or have a like/dislike button in resoect to your petformance/activity
Forums are easily accessible for all KaW players. Spread the word about my new thread and it will be known to those who try hardest to join a war clan. I would rather have a try hard on my roster than someone lazy and careless.
