Multiple cleric spells at that. Cleric spells, which weren't designed or sorted with metamagic in mind... Distant Inflict Wounds, Twinned Guiding Bolt, using sorcery points to shuffle around/empower/twin healing spells, Heightened Bestow Curse, Distant Bane followed by Quickened Fireball? All sorts of nutty combos.
But yeah, UA version was definitely nuts. Divine Soul is now within somewhat more reasonable limits of nuts. Once-per-short-rest +2d4 to a failed saving throw is still pretty sweet for a first level ability, on top of Cleric+Sorc spell list shenanigans.
EDIT: Right, so, for the beginner's group, I'm kinda leaning towards druid. Specifically; Circle of the Moon, Variant Human picking up Charger at 1st level, high WIS and Shillelagh for when I'm not shaped.
All I know about the group is that the DM is inexperienced and the players are also either inexperienced or complete first-timers. I want something that can carry its own weight and preferably be able to fulfill some amount of a support/healing role just in case everyone does indeed end up acting like they have a deathwish (something which is only very slightly less common in more experienced groups).
At the same time, I don't want to have a character that's a bit too optimized and that bowls over encounters before anyone else gets a chance. That's not fun for anybody. Nor is a helicopter healer who heals everyone before they can taste a little risk.
Druid has some decent support/utility spells, and even gets Healing Word along with Cure Wounds. Charger is far from an optimized feat by any means, but it does gel a bit with some of the Wild Shape forms and Circle of the Moon shaping is already pretty hilarious at low levels as it is. It's a lot of single-target alpha strike ability, but it's not "I cast Fireball, thereby deleting the encounter". I'll even have good WIS for perception checks so we don't fall into quite as many pits. I'm also not quite squishy enough to warrant them having to look after me. Provided I don't get too cocky and sure of myself, that is... Definitely no guarantees there.
It's also single class and doesn't rely on too many confusing rules or wordings (the Crossbow Master bonus attack, Twinned Spells, or anything related to mounted combat on large creatures...), making things easier for the DM, and everyone else for that matter. Heck, I don't even know yet whether or not multiclassing will be allowed, or feats/Vuman for that matter. But it's a concept, at least... It can do a few things fairly well, and it's goofy enough to get me interested while also being punchy enough to appeal to my desire for combat optimization.
An alternative would be a Thief Rogue with Healer, taking advantage of the Thief's expanding upon Cunning Action. I just have a hard time balancing all the stats and skills as Rogue...
