If you make a post on this forum and someone disagrees with it I don't think that isn't a personal attack.
I had thought your group was capped on 12 and approaching 13 --- my mistake. I also didn't know it was three.
Firewall was nerfed back in mod 6 or 7.
The problem with FW and other AOE spells is that the AI of the monsters needs to be adjusted. Intelligent monsters need to react intelligently while those monsters such as most giants, ogres, trolls etc who use rage probably act pretty much like they will. I doubt Joe Ogre is working on nuclear submarines in his spare time.
Fix the AI and let the spell do what it is intended to do.
Regarding PnP style - I like to 'emulate" (to rival with some degree of success) that style in an MMO. I chose that word carefully when I put it into the mission statement of VPDG.
If I were "copying" not "emulating" do you think a Drow Pal/Ran/Rog would work too well without enhancements. Yet, I run that blend as well as other blended classes that probably wouldn't do well in Pnp.
With the enhancement system you can make builds that are "too good to be true". That is part of the fun of this game. Also, my knowledge of PnP is from AD&D not 3.5 which is hardly the same game. I flipped when I saw Drow as player characters!
Again -
I think the elite only group is a laudable effort and I wish your group well.
