This and the fact that mobility dodge AC is a non-issue (as someone with tumble 15+ will not succeed in ever using it even if they tried) made me wonder why the limit was relevant. No biggie.
I am interested which other mage spells give dodge AC though...enlighten me.

The spells i had in mind were Epic mage armour (+5), mage armour (+1) and haste/mass haste (+4). As i said, that's a +10 since both mage armours stack. You can get even more than that with some exploitative use of shadow conjuration (yes, it can be done if you do it right but i'm not giving info about exploits in an open forum

).
About tumble and mobilty, there's a serious misconception out there.
Tumble doesn't make you immune to AoOs, period. Tumble will help you to avoid AoOs caused by movement in combat but if you drink a potion, cast a spell, attack unarmed without improved unarmed strike or shoot a ranged weapon in melee you are not going to get a tumble check to avoid the AoO caused by this, you are going to eat it no matter how good you are at tumbling. The enemy will roll his attack and if you have mobility you'll get +4 dodge AC, quite relevant for a caster or an archer. Mobility is a useful feat even though most people just take it en route to spring attack or to meet the requirements for the shadowdancer PrC.
EDIT: And anyway, my point was that if the dodge AC provided by tumble and expertise counted towards the cap, it would be extremely easy to hit it and the improved expertise feat would become less desirable. Since this is not the case, i don't think that too many people in Avlis are going to have issues with the dodge cap any time soon.
