Quit hanging on every single word as if it's set in stone and you might not be so confused. Look at the overall idea: Give the mobs some more fortification, and give us some options to reduce it. Simply swinging a wop may not cut it, you may have to do some other things or rearrange some enhancements to reduce fortification enough to make it worthwhile. It might be in some cases or builds that it's just not worth the hassle and you'd prefer straight dps instead. Or maybe it would give intimitanks something else to do mobs instead of just intimidate-turtle.
This is the "suggestions" forum. Those were a few that were thrown out. There could be multiple ways to reduce mob fortification; enhancements, weapons, feats or abilities. Obviously, rogues get hit doubly hard with mob fort. Both sneak attacks and crits are reduced, as well as stat damage. Maybe they need an enhancement option to help. Anyone wtih crit focused enhancements get nerfed somewhat by mob fort as well (barbarians, and some fighter, pally enhancements). Perhaps they'd need to pick up a weapon that reduces fort in their offhand, or use an ability like sunder to reduce fort. Again, these are just suggestions. You don't like them, modify them, add to them, come up with something else, rather than "B-b-but you said only such and such needs help. Why must they get help and not others?". Take the idea and run with it... or not.
