Fire spell on hit improvments

Hello exiles,
I am playing around with smith of kitava and it's very nice tankiness wise however the damage ascendencies are a bit underwhelming. So let's talk about fire spell on hit.
My main issue is the requirement. I believe there is 3 options:
- Remove requirement for triggered spells.
- Heat of the forge also gives "Fire spell requirement can be satisfied by strength"
- Chnage to fire skills on hit.

My favorite is 2nd option. You could do some funky stuff with Iron will and it will make you able to play strength stacker also on spells.

Yes, as a warrior being forced to play full intel is a big nerf

The problem isn't so much the attribute requirements, which can be met relatively easily, but rather what to have in the gem so that it has meaning either as a damage buff or as damage itself. As a warrior, you'll never have a bonus on spell damage or plus spell levels to make this more meaningful as direct damage.

In the current league, I'm running Fire Spell on Hit, and there are only a few spells to put there to make it meaningful.

Volcano - can't be used because it's channeling, even though it would have nice synergy with my Bear druid.
Flamewall - lousy damage and buffs projectiles that aren't very playable with a warr.
Fireball - lousy damage
Living Bomb - small damage, fire infusion generator, but there's no way to use it to make it meaningful.
Ember Fusillade - poor damage and strange behavior due to the fact that you have to pause attacks for the shots to fire.
Snap - Can be used as a clear ignition on a character but poor damage.
Elemental Weakness - This spell is a decent buff and I use it
Incinerate - Cannot be used because it is channeling
Firestorm - Poor damage and also resets on recast because the limit is one storm.
Flameblast - Cannot be used because it is channeling
Detonate Dead - This spell does decent damage because it is cast from the Life of enemies, but it is also cast on corpses, so it increases the clear speed on the map, but it cannot be used on bosses and I use it.

There is nothing else, so I conclude that there is not much choice for casting other than the INT requirement itself.
