Strength Tanks

[Uhm]

I guess all this comes down to is playstyle, I don't have to do massive DPS to think that tanking is fun and right now I'm also not doing any high level raids, but I don't quite get how healing could be more interesting without the possibility of also doing DPS (you could say I shouldn't heal then, but I like healing+DPS). That's why I obviously like Tanks that don't take unpredictably huge chunks of damage suddenly better, and I assume that is easier with more Vit.
As a tank I also don't have a problem if the healer lets my HP fall as low as they feel comfotable with without letting me die, benefit of more HP. That being said I am packing more strength on myself since that seems to be the trend.
All this also depends on the situation the tank is in and his skill. In Duty Finder playing save is always better, what works with people you know might not work with people in Duty Finder and suddenly the srtength tank in Deliververance is dead faster than he can click Holmgang because the healer just woke up and wasn't prepared to spam Cure II on him while the Dragoon/Blackmage stands in AoEs and the Bard exidentally pulled three more mobs with his auto-attack.
Is healing and tanking in other games a lot different? My brother asked me to level a WoW character for him once and I was surprised to only find healing spells on his hotbar at that time... he also seemed to think it was weird when I mentioned stacking more Str as a tank.
