Shifters are pretty good under storm, no doubt. Area evo is the most obvious solution. Even under storm enough archers will still give them problems, particularly with flaming arrows/wind guide. They've got a measly 10 MR so any magic resist stuff will give them problems - curse of stones, winds of death, shadow blast, bloodletting. Forge a few banefire xbows and hit & run from behind your PD, you'll be surprised how fast they thin out. Their morale is only 12 so fear/terror/panic spam is another option. Melee with them is not generally where you want to be unless you've got top notch units yourself, but keep in mind they are 25 gold apiece so you can sometimes win on a gold basis even taking 2:1 losses.
