How many of those are you REALLY going have going at the same time though? Its a very niche build you're discussing. [...]
Actually, that's not a niche build, that's a niche PARTY.
Well, considering the historical precident we have from 3.0 and 3.5 when different named bonuses would stack, players will go really far out of their way to get them. And with bounded accuracy meaning that the modifiers and DCs are in a more constrained range, every +1 means more in 5e so you don't need too many sources. 2-3 on a roll will make a big difference.
Do I think it will make difference at every table? No, not at all. Though a simple guidance or bless + bardic inspiration is likely something that a good number of tables could pull off.
Do I think that some parties will have lots of different type of numerical buffs / advantage? That I do as well.
And for what? A couple bonus re-rolls, and a couple 1d4s added to it (plus the scaling bardic die). Its a trick that requires an entire team to pick exactly the right combo of skill-pumping abilities and then dump them all on the one PC. For one skill check. You think that's bad, don't check out what a well-optimized party can do to aid the team fighter in combat!
The reality is that few, if any, PCs are going to have more than two of these effects going at any given time. Even if the perfect storm hits and a PC somehow gets a 40 on a skill check, think of how many resources were wasted to do so. Let the guy beat the DC by 20+; its not like he's any more successful for beating a skill check by 2 or 22.[/QUOTE]
