Allright! Since I raised the topic of trying to co-ordinate our Skirmishing attempts, here's a thread to discuss that very topic. My advice is this... that we carefully choose which soldier 'type' to put our efforts into levelling with marks, so that when it comes to Skirmishing (solo or otherwise) we stand the best possible chance. This can be done by ensuring that every role is filled by someone or their ally. If we can each concentrate on one class of ally - they'll level quickly, and give us a better chance of trying Tier II or III!
For Felaion, I've chosen to level my ally as a Protector. Hence - a tanking role. I've chosen this because in solo-play, the tank can hold aggro whilst I deal increased dps from behind. As part of a group, the debuffer/tank combo means we can keep multiple foes out of the fight, whilst the dps do their job. That does rather mean, that in team-play, my job is crowd control.
