I think ill do this...
 

ok so im a cleric and im going to solo at calapse prison at some stage like i saw someone doing but i was thinking maybe go full End? i mean it does
1.save ppl thinking too much
2.last longer when you get aggros from healing

and wouldnt time = more dmg? so maybe def will balance the dmg intake/delt?

well I'm a lil confused by how you wrote what you did, but if you really do intend to solo, then I'd suggest going with the END. If you need dmg and all that then you can make it up with rings and other equipment items.

plus you get more time to attack since you don't have to worry about you hp as much as you would if you didn't go with END, giving you time to rechagre your Bash which is your dmg moneymaker

It is time inefficient to have full END. You will take less damage in the long run, but you simply won't do enough damage.

Honestly, it's really not that slow. I am a patient man and full end is quick enough for me.

Yeah, currently on my Cleric at level 27 I have +5 dex (dump all 5 points into dex after job change), +22 End, +5 SPR. Personally I wish I stuck with just full end at times. Yet having that extra bit of aim/evasion, sp/crit does help a lot too. The best thing I can suggest is to feel out the character and truely spend time to understand your character and what it can handle. Hybrids like mine are just as fun as full end/str/spr clerics.

I'm just wondering how many people can actually solo all the way though. I always get the impression that at level 50+, it'll become pretty tedious and boring to solo. =/

Hmm...Well to be honest I made this Cleric specifically for solo play in this game as I have limited game time as it is. Other classes solo eat up funds quick and quiete frankly, die easily without support heals. Knowing that I can quickly and easily heal myself and continue to dmg. Clerics have it the easiest for solo play. Even at higher levels I'd have to assume the same.

Yeah that is true. xD

I've found I can solo orcs at lvl 34 with my cleric. Stats in END fully cept for 6 in SPR. Granted I had a cleric buff, vit scroll, def scroll, and power (tier 2) scroll.

Pretty fullfilling though if you can pull it all off (despite taking out a good deal of my hp stones) and it takes a while as well

I highly doubt it is time efficient to solo orcs at level 34. Economically speaking, it is a disaster. If you're even able to survive more than a few hits, your damage per hit will be incredibly low. Not to mention you'll burn about 5 stones in SP alone for heals per orc.
