Well, there
is a preset called battle mage
This preset should have a staff as default weapon to be a viable choice. Makes no sense to use sword. Anyway, the most useless gear I saw were STR-based armor pieces with +FIN and vice versa. There's no build where it'd be beneficial. Not that +5 INT sword is much better...
To be honest, this is the only hybrid preset that I actually uses in almost all of my playthrough. Two reasons:
1. The fighter and knight preset are terrible. Contamination is suicide bomb that does not kill enemies. Rage is not strong enough to cost 2AP.
2. Although I don't put points into int for the battlemage. The CC still works 100% if you have another mage to burst through magic armor.
Being a hybrid, the battlemage has trouble standing on his own with stat spread thin. So I build him like a normal warfare fighter (with STR), but start with 2 magic CC skills.
