I'm thinking after being defeated how about needing to wait 60 seconds before you can mount a Warclaw? Just thinking of a time I was taking a camp, one guy was trying to defend it, I defeated him a few times, they had claimed it for fast Dolyaks, so whenever one spawned the capturing stopped, then he was able to get back on his warclaw just in time to stop me finish capping. I was using some stealth in this build so that was able to decap my progress. Dolyaks running really fast so It would take me quite a bit away from the camp if I'd pursued.
Before the Warclaw if you defeat the one guy defending a camp unless another enemy player shows up that camp was pretty much yours. Putting a cooldown so you can't just summon a warclaw straight away would help get it back to the way it was.
Faster capping, we can now travel to points a lot faster than before. To bridge the gap in balance this can cause between offence and defence filling the circle faster might work.
Taking away the ability for Dolyaks to contest points. A fighter riding the warclaw needs to dismount to contest. If a war mount can't contest why allow a transport Dolyak to? Guards would still spawn and contest but Dolyaks would just spawn and run, or become hostile if the objective they are supposed to supply is owned by another server, not contest.
One other idea but it would quite significantly change the way things are, after being defeated needing to wait 15 seconds to be able to respawn like in PvP.
