As Meta-Physicists, despite our nearly super-powered control over our emotions, I'm pretty sure we're all getting sick of getting team invites to endgame content pretty much only in the following situations:
A. It's a points bot and the rules don't allow MPs to be excluded.
B. It's HI, IS, Ice Golem or Inf Garden Key PBs (meaning NSD works and is needed).
C. Our friends/org take pity on us and invite us (even if they could have done whatever they were doing with just the core professions).
The reasons for this are quite well known also. There are basically 4 important team roles other than DD - tank, heals, reflects, crat initiative debuffs - leaving 2-3 spots for primarily DD (though other contributions are welcome if they come with the DD). Crat initiative debuffs are getting nerfed and moved into the same line as UBT, so subtract that one from the post re-balance list, and we're left with 3-4 spots for the non-essential professions (including MPs).
We need some reason a rational team would choose an MP for one of those spots. Going from our most recent nano-document, we'll be somewhat more useful to a team (assuming it isn't one of the handful of raids where NSD works at the moment) after those changes than we are now due to improved DD from much better nukes (and likely somewhat better pet DD, though that's speculative), vastly improved healing (though not Doc level), and debuffs that will land on bosses (NSD up 25% of the time is better than NSD up 0% of the time, particularly combined with -70% nano-damage modifier 1/3 of the time, heavy damage debuff up 1/3 the time that doesn't over-write something more useful). However, all of that may well not make us as useful as a pure DD profession such as crat, engineer, NT or shade, or as a profession that could switch to one of the primary roles in an emergency, such as Adv or MA.
Alright, of ideas for improving team desirability the two that seem to have generated the most discussion are improved debuffs and team nano regeneration. Two other theoretical ultra-longshot possibilities would be DD on the level with good DD profs and and some method for filling the primary healing role in a team (my idea there would be a nano that gives the heal pet a 150% heal modifier and the MP a -1,500 AAO and -80% nano damage modifier, or something like that). Those two though don't seem likely at all.
Option #1: Improved PvM Debuffs
Option #2: Strong team nano-regeneration
Option #3: Strong DD
Option #4: Some way to fill the primary healer role at the cost of DD
Option #5: We'll be fine with the changes already in the nano-document
Option #6: Other (to be explained in post)
I'll pass the results on to the Devs. Personally I think Option #2 is our best bet, both from a general utility and a "likely-hood we'll actually get it" perspective (but I'm not going to vote).
Thanks in advance everyone!
