Roll20 even for what is presumably the best-supported game (DND 5e) has completely unuably broken UI. Something as simple as equipping a piece of armour is an excersise in trying 5 different things, let alone trying to wrangle magical items into the system or get the hp bar to be accruate which almost never works. It takes far longer to teach somebody to use the character sheet system than it does to teach them literally all of the rules of DND, and even then it consistently finds new ways to unexpectedly fuck up stats and bonuses at a rate of about 6 or 7 times per session. Overall, If I must run an online game, I just use pdf character sheets and just have players /roll d20s in chat and ignore all the roll20 functionality as its such a nightmare.

Overall, in trying to reduce the complexity of the game, they gave you a finnicky spreadsheet nightmare of half-baked solutions to problems no-one had.
