Patrik, getting a storm going doesn't work well if you're relying on crossbows, it hoses their precision and causes half the shots to just get lost outright. Similarly, it sounds like the unit of choice is woodsmen, which are lightly armored and have no shields, and thus longbows (especially with flaming arrows) would be the ranged attack of choice.

I'd go tower guard to resource max and then fill out the rest of your gold with longbows, make sure to get flaming arrows...phoenix power burning a gem to cast and then another 2 gems to get off flaming arrows should work

What bless is he using? If he's not using fire bless you might want to try to find some high defense units to hold the line, if he is just suck it up and try to kill him first. Your guys will get hit, and they will die, don't worry about prot. If he's using E9 (or even if he's not) toss some destructions at him to pop his armor, it'll help a lot. Abuse PD if you know he's going to attack somewhere, fodder is good (especially if he has no earth bless for reinvig). Water bless will help, but you get multiple attacks on him which will bring the defense score back down, and it's not stellar to start with, you just have to out-swarm him.

Destruction works wonders though, try that out, plus longbows and the obligatory wind guide. If you're going tower guard make sure to get sermon of courage off so they'll pass their repel morale rolls as well...the one damage won't matter, so as long as they're not losing attacks to it they hit harder than long spears and have the defense to survive the occasional swing, especially if the giants aren't high fire bless.
