Sadly no fighter today, no time, no motivation. So I just randomly picked a short topic from my memory and ended up with: The easiest subclasses in the PHB!
Sometimes there will be a player, who either doesn’t have much experience (D&D or P&P generally) or simply just fails in the organization/memorization/etc. department. But there is no need to fear, since the PHB actually got it covered. Some classes are more difficult to play than others (like the druid, who isn’t bad at all, but need some cautiousness), but generally no class just makes you better: Most features are situational and restrictive, so even with the easiest combo (feature-wise) it’s still more complicated than other systems. I’d like to say, that class-feature-wise, the 5e is even the most complex edition of D&D so far.
This is simple a list of the easiest class – subclass combos from the most difficult to the most easiest one. I assume the basic care of the specific class (to read and understand all the spells, decide between several options, etc.) and don’t add the basic playability to this, since the complexity of the fighter-class and the complexity of playing a fighter are different matters (since a fighter as a front-character have a lot to worry about and one or two wrong choices might get your teammates killed).
12.) Druid – Circle of the Land: This might not be surprising, but the situationality of the spells and the wide variety of spells and wide-shape makes even the more easier druid a quite complex class, as long as you do even care a bit.
11.) Bard – College of Valor: The bard is a monster in terms of utility and variety, so of course he’s more complex. If the druid wouldn’t have wild shape which meant to look into a lot of additional future rulebooks (like the MMs), than the bard would be definitely up high. And it helps that other classes do have some spells so great, that you don’t actually research that much when hitting a Magical Secret.
10.) Paladin – Oath of Devotion: Being a paladin is an ordeal. Not only the vast spell-list, but so many options and choices you have to face every turn and often even outside of combat makes it simply hard to actually play the paladin, while his features are a tad lighter in terms of complexity. Some are kind of forgettable, but might be useful too often to do it with a clear conscious.
9.) Wizard – Evocation: While the wizard class itself is easy, the spell-list is humongous. Reading every spell might take a while and you can even prepare them…
8.) Warlock – The Great Old One: Down to it, the Warlock is almost easy in comparison in terms of complexity, since after choosing your stuff, you’re pretty much stuck with it, while only the selection procedure will take time. But since there are pretty much options here, that aren’t played by the same rules (when to regain, how often to use, etc.) it isn’t as easy as the next one imo.
7.) Cleric – Life: Since this domain only applies to one aspect, it’s much easier as a cleric. But still, the spell variety kicks in.
6.) Sorcerer – Dragon Ancestry: From all the main-casters, the dragon sorcerer makes up with easy to understand features and a not too complicated spell-list. Even though you still need to read a lot of them.
5.) Ranger – Beastmaster: After the initial decision, the Beastmaster is easy to handle, you got your companions hardstats and if it weren’t for the spells, he would even jump right ahead to 1st place.
4.) Rogue – Assassin: Now we’re down to the no-spell class choices. The rogue comes as third, because even though his features are much easier than reading a lot of spells, you’ve them all over the categories. The assassin was picked, because two of his features are so situational, that they might be forgot and/or never used.
3.) Barbarian – Berserker: The Barbarian should be a simple class, but most features remembers to the rogue, some variety and even if you don’t have much choices to make, remembering advantage on DEX-throws,
2.) Monk – Way of the Open Hand: The monk isn’t easy to play, but easy as a class. The only resource you actually have to manage is KI, but somehow the class still has some options to use these points and how which feature interacts with another one.
1.) Fighter – Champion: Some might suspected it already, but the reasons are really easy to understand. A lot of straight features which applies any time, while the rest is almost every time about when things get tight. It just does what it does and is almost every time easy to apply.
