Determination is an ability that reduces the duration of crowd control spells by something like 80%, I forget the exact number.
Charge makes you immune to crowd control and makes you run at speed 3.
Casters are completely pointless against charge groups as you just get steamrolled over, you can't crowd control them and they're faster than you. Even if you do get the drop on them first, Determination means your CC lasts 4 seconds and then they just hit charge and roll you anyways.
All 3 realms can run charge groups but I'm fairly certain that in 1.62 only Midgard got celerity buffs. Since Midgard has the highest-DPS melee classes to begin with and haste stacks exponentially in DAoC, they're probably doing double the DPS of everyone else.
