In case you are thinking about keeping the NEC and going more caster heavy...I ended up going with PAL, DRU, ENC, BRD, MAG and NEC based on another post here on RG that I saw recently. Only level 101 atm (on Test), but my Druid has had zero problems with healing, even when in 'Hybrid' (DPS + heals) mode with the CWTN plugin. I've also not had any mana problems at all, which I'm sure is due to having 3 classes that can help with mana (BRD, ENC, NEC). As far as the overlap between ENC and BRD goes, I was a bit worried about that initially, but having the ENC focus on CC and letting the BRD focus on ADPS is working out pretty nicely. I love the CWTN plugins and the MQ2Bard one is a huge upgrade from messing around with KA all those years, but watching my ENC (also with CWTN plugin) handle any # of adds, while also charming, DPSing, throwing runes, etc.. is pretty sweet to watch. I initially started out with WAR, SHM, BRD, ZER, ROG, BST and had at least 6-7 wipes with the bard trying to lock down multiple mobs with CC. Granted that was at low levels (sub 90), but I haven't had a single wipe due to CC issues with this group using the ENC as the only CC'er. It really is amazing how good the MQ2Enchanter plugin is when it comes to reaction times and keeping mobs locked down.
I ended up switching my group composition for multiple reasons, but like you, the convenience of ports, evacs, etc. was one of them. Is the group super optimal? Obviously not, but I'm having fun trying something different than I have before. I've done the whole SK, SHM (or CLR) + whatever else route many times and wanted to mix it up a bit this time. As Sic and others have said, at the end of the day, it should be about having fun. That obviously means different things to different people, but having a group that always parses top DPS isn't my main priority anymore. Discovering the synergies between classes that I haven't played before (PAL + DRU) in this case) is keeping me engaged, which is all I'm looking for at this point. I look forward to seeing your progress as you get your new team going. Good luck out there!
