due to time constraints and off-hours play times being the norm for me now I've had to take a hard look at some soloo builds that fit my (quite low) in game budget. The first ones I've looked at of course are the ever-popular solo monsters: 18 / 2 cler/monk or Fvs/monk. Pure FvS are apparantly quite strong soloists at high levels as well with that nice capstone and other lvl 20 bonuses.
However, as I mentioned above, I'm quite lacking in the resources and time to attain some of the high end gear those builds use to attain their high thresholds. So I was looking at rolling a melee capable but caster-focused 19/1 dwarf cleric. The level one splash is fighter for the extra feat, tower shields, and dwarven axe proficiency. From many of the posts I've read, the first mentioned builds have been able to solo pretty much all the game content, including many raids all the way to 20.
I'll be missing evasion but the pure 20 FvS doesn't have that and is considered a mighty soloist so I hear. I won't have the FvS's spellpower but that can be worked around. I won't have as high saves or AC as monk splashes, so I'll have to brute force heal past some shortcomings. My question is, how wide is the margin between those builds and a 19/1 build for pulling off soloing all the way to 20? I mean is it significant in actual gameplay or is it minor enough that it only matters in the world of forum theorycrafting?
