Dodge can exploit weaknesses in AI if not taken into account.
A high AC character can dodge past foes to draw OA for rest of party to not need to disengage. If the AI fixates on a PC you can use dodge to leverage better action economy. This gets exploitive if the party is ranged with one high AC dodger drawing agro. Then there’s the end of fight where the repetitive smart money is to just dodge while rest of party chips foes down.
The concern with this is real. For example if stealth stays on a bonus action and the AI is as bad on release as it is now at finding stealthed characters, it is very easy and boring to exploit dodge.
Ready action should be a thing though, if only as an overwatch mechanic. The shared initiative we can sometimes take advantage of is not nearly enough. It would reward positional gameplay in a more satisfying way. Maybe the AI could profit here as well, since it does feel a bit dumb when everyone and their mother just dashes on top of my fighter or paladin when they can't get in range to attack.
