What he is saying is sure, put on that bit of armor, thw wot mage simply removes that somehow and you are back where you started essentially vulnerable. so yo prevent that you have to prep protection again. which the wot mage is going to remove yet again. so the concern is how deep to have protection.
the solution is to have some depth, which could be some of the mentioned approaches. one round, double protect, so the wot mage has to counter both. one should always be un unrevealed enchantment. because now the wot has to be concerned it is a nullify. by dbl protection, you get a chance to see what he does. allows you a break to forward your own strategy. learning how to play aginst the wot mage really elevates your strngth as a player because it helps you learn tactics. that is a real improvement for a player. it helps you look at the game differently than the casual player. you have to think a few rounds ahead.
forge, armor, eagle boots, nullify. are just a few of the protection options. and most of those are useful against all mages, not just a wot. so your one qrtr spb is not accurate, since some protections are more generally useful than just against one build.
