By default, a touch-range spell has a 3 meter range. That's within the range of of any other melee weapon attack range. Yes, it can be extended to 5 meters... by spending a Talent. Isn't that what Talents are for? You spend points on them to get a special bonus.
This is not D&D and does not have rolls to hit with spells, let alone two rolls for a single attack. That might be something to consider for D:OS 2, but it's not likely to be changed in a future EE patch.
You get a special bonus, which should have a sense. Right?
Does it make a sense to make a skill "Long fangs" so its extends daggers range to 6m?
You get a special bonus which should be a special, touching spells are special by themselves. They should be dangerous for the target and for the caster to come to close. That is tradeoff to consider. Give them a range so make it a common.
Touch spells should have same range as daggers.
MAAAAAAAAAGIC. MAGIC. Spells are not normal physical objects with a fixed size.
Now I'm going to stop the argument here to avoid derailing the thread any further.
