Just saying monsters had it too since forever and only 4e made the more ubiquitous OAs
what penalty? from the d20 SRD
Charge | Move up to twice your speed and attack with a +2 bonus |
I have no clue to be honest.
5e making it easy to get places once everyone is in combat is kind of a complaint I have heard against using the 5e flanking rule. And to me a reason to make opportunity attacks more available. But charger just isn't that good removing it is a subtle nerf but it compounds with others in my opinion. In 4e the charge was triggered by Warlords and a set of magic items enhanced them tremendously (called a charge kit).
We could still have a Charger feat but it would do things like allowing the charge free when an enemy went down so you could charge to another target .... and allowing it without triggering opportunity attacks. A charge so enhanced is then feeling like you are a missile weapon yourself almost and particularly with a long arm throw of a javelin that returns. This would replace the Charge Kit in effect or on could introduce Horned Helms/Badges of the Berserker and the like instead for another style of fun.
Charger is ranked really poorly among feats, as feats are supposed to be big things... especially combat ones that are competing with the big ones.
