Well, just for this topic I made both a Wizard/Cleric and a Wizard/Bard build to level 5x so far (both Fully Farmed and with EVERY move maxed that I can). And I am not bothered to get them higher level.
And my answer? I find it is comparing Apples to Oranges. They just generally play differently. Yes, the Clerics Bless and Recovery Division make for a better survivability. But so does the Bard's Noise.
Yes, the Cleric can "tank" a little better when it comes to party/giants. But Bards won't get swamped by other monsters while fighting party/giants either. Win Win for both builds. (By the way, I did find Earth Barrier to be very useful while fighting giants. Just no one seems to mention it).
Botting wise the both died on avarage the same amount of times (and yes, I botted in the same area. Well right next to each other). And I am keeping in mind this topic is about botting and not playing by hand.
