I've been exclusively playing a capped cleric so far. So I'm not totally noob on cleric topics, but I am utterly clueless on multi-class discussions. So please feel free to correct me.
The question is: are there really any strong arguments for not splashing at least 2 levels of another class on a cleric now that mod 9 is going to be released?
I'll try to state what I think are the arguments and counter-arguments in each case.
POTENTIAL BENEFITS OF STAYING PURE CLERIC
1. More SPs and/or more HPs (potentially)
But it depends on splash
2. More high level spell slots
But quite frankly there are 2 really useful level 9 spells, maybe 3 (mass heal, implosion and negative energy)
3. Cleric capstone
But it seems like it's not that useful - unless it is designed for very specific new quest content
4. Prestige classes
But still achievable if splash is 1 or 2 levels only
5. Higher spell penetration
May matter a fair deal to keep BB and Destruction viable, as well as Implosion
POTENTIAL BENEFITS OF SPLASHING 2 LEVELS
1. Melee capability
With paladin or fighter - the infamous battle cleric - let's not start a debate, but acknowledge that some players like the build
2. Evasion
With rogue or monk - increases survivability (monk also adds wisdom based AC bonus)
3. UMD
With rogue or monk - adds a bit of versatility (e.g., teleport and stoneskin scrolls)
4. SP
With sorcerer
CONCLUSION
Based on the gameplay as we know it (i.e., excluding potential future capstones, etc.), it would seem to me that based on the relative benefits, the choice should be based on the style:
1. Caster / Healer - stay pure to get max spell penetration and extra spell slots
2. Healer / Caster - splash 2 monks + halfing to get survivability and mitigate SP loss by dragonmarks
3. Battle cleric - no other choice than splashing (without entering the debate of viability)
4. Balanced / flexible build - splash 2 monks + halfing and respec between dragonmarks / caster feats as needed
