Can someone explain this?

Monsters and Metins have resistances to weapons just like your character might have. It depends on what you are killing. Usually monsters have more swords resistance than two hand resistance.

Sorry for the digging, but the issue was:

FMS dismounted: 100 hit

FMS Mounted: 80 hit

It should be the oposite since the horse adds up stats, "When I am not mounted, I hit for slightly more with the FMS (30-50) but then when I mount I hit less (80-100)."

I actually its weird

Horse doesn't add stats, but raise to a certain number. To explain better, it makes your DEX 71, it doesn't add points to DEX, so if you have 71 or 72 or even 90 DEX it won't do anything.

Bottomline, the damage between foot and horse, can be the same, but not lower, if it is lower there is something wrong. But without any data shown I can't really answer.

Shadow when players talk about stats, it isn't always stat points, but anw, the data can only be provided by the thread owner since i never experienced any issue of sorts

When player talks about horse, the difference can only be status points, as the horse doesn't provide any hidden stats (remember horse not power mount). If your STR and DEX are high, the horse won't provide any benefict to your damage because i explained earlier how horse boost stats. So the damage can be the same and not lower. Since you were necro posting this I thought you had an issue and not just commenting what the thread owner said, even because his issues was not with 2 fms, but with 2 different kind of weapons.
