I have like 3 problem with druids lack of spelsl that have no concetartion... Some of them could be tweaked...
Yes, it hadn't really occurred to me in this run as I actively
wanted spells with concentration that would confer benefits over a number of rounds while in wildshape. Well, spells that confer benefits over a number of rounds without taking concentration would be good too, but I don't expect many of them as one of the points of concentration is to make sure we don't break balance by having too many longer duration spells running at once.
But I imagine I would have noticed the lack of non-concentration spells more if I'd been a land druid.
The spell casting version of it and how it has the same problem as the wizzard with arcane recovery. It is useless due to how rest works in game they really need to make those two skills useble in combat. .
The way I played my moon druid I didn't find myself running out of spell slots as quickly as a land druid presumably would, as they basically cast a concentration spell, transformed, then didn't use any spell slots unless they needed to lunar mend until they were human again. It actually felt reasonably balanced in the sense that I tended to run out of wildshapes and spell slots at roughly the same rate so tended to need to rest anyway, though obviously with only two level 3 slots at level 5 I had to save those for what I expected to be the bigger battles.
Though the ability to regain a spell slot or two as per arcane recovery wouldn't go amiss, and an item that granted a version of something like it for druids (or just everyone who used spell slots including wizards for an extra boost) sounds like a good idea as long as it came at a point where it wouldn't break balance. And now I'm thinking I'll want to experiment with Spellthief when I get round to the wood elf land druid run I have in mind!
I'm not sure about using arcane recovery or any equivalent in combat though. That does sound balance breaking.
