I did indeed think about this option. In the end I decided against it for three reasons:
1. I like swords and with sword the fighter stats seem to be Str/Dex
2. I like 2h fighting and it seems to be inferior to 1h+shield. As clerics have no shield proficiency it more easy to justify going for the inferior option because I can't use shields without spendng a feat anyway
3. If I am the healer I don't risk ending in groups without healer (my last RPGA game was such a kind of game, the only healing the group of 6 characters had were 5 potions and 3 healing belts

)
So my goal is to find the stat mix which gives me the best combination of melee progress (plan to use a bastard sword 2handed) and healing ability so that I can have fun hitting things with my big sword while still healing whoever needs healing
