In early access where level 2 spell slots did all your damage as a druid, if really was downright useless. Either barkskin needs to be level 1 or Level 2, but require no concentration. Aside from buffing AC by 2 instead of setting it to 16.
You can RP that way, but that's just... you might as well RP as a battlemaster only resorting to their fists for damage. Or, a paladin only using crossbows.
Like all druid melee concentration spells so far, it can be lost by stepping on a surface -- which is frequently -- or being hit in combat. Playing around with flameblade taught me early just how wasteful this is.
For half of early access, you have exactly 2 level 2 spell slots. You need them both for one mildly difficult fight. A frail druid better moonbeam all those ranged suckers twice a day.
Of course, some druids eventually also get haste as an alternative to cast on allies. Haste potions are yet everywhere, tough.
