Potential issues: Skirmishes might become more fun or more played than the rest of the game like WAR's battleground thingies. (I forget their name.. its been a while)
Skirmishes might suck on the other hand and just be something nice that they tried but aren't really compelling. A lot will hang on the fun level and the reward tuning. It needs to be on par with instances for fun level and slightly below them for rewards because instances are harder to arrange a party for and harder to lead and yadda yadda. Still the rewards need to be better than for the silly Angmar thingies they did which were quite hard yet had no significant rewards compared to the instances.
Last but not least.. they need to copy Champions Online and do skirmishes with pvmp mixed in. That is all.
