You could create it in 2E, though you'd spend a lot of your time just standing around in the back and waiting for people to get hurt. Priests did gain bonus spells for high Wisdom, after all, and it's as likely (or moreso) that you'd have a high-Wisdom priest as a high-Strength one.
Does it really seem weird that we'd make a distinction between giving an ally +2 to hit, or giving an enemy -2 AC? Do you not get how it feels way different?
You can create it in 5e just the same as 2e. Take nothing but healing and buffing spells and stand around waiting to be useful. If your not useful enough, talk to the DM about upping the challenges so that you are more useful.
