But anyways, most of the people responding, including competents turned fuckwits snakeman and lycan are the biggest reasons I am convinced I made the right decision.
So far what we've been doing is mentioning practical, inexpensive, and, (dare I say it) mundane methods of defending yourself.
For example, at level 9, not everyone has Protection from Evil up all the time- the duration is too short to make it practical. Magic Circle is moreso, but still only lasts 1-1/2 hours and, to recieve the benefits, you're AoE bait, once again making it fairly impractical to actually rely upon it as a defense (unless you are the caster). Mind Blank is still several levels away. But Dominate Person is on the field. A basic disguise will probably protect you from it (most Wizards don't have great Spot checks) or get it wasted on you (if you're, say, a Warforged masquerading as a human which may be for a reason completely seperate from combat) instead of your allies. This is possible with virtually no resource investment but time. Just take 20 on the check and you're set. No, this is not a perfect defense, but it costs you nothing but some time and has the potential of protecting you from not only type-specific spells, but also unecessary encounters.
Yes, magic still wins D&D, but mundane is nowhere near as helpless as you make it out to be.
So, I apologize that we're concerned with practicality and how most games actually work here. We'll try to be more focused on just numeric win from here on out.
