If they did hard cap it, do you think 60 would be a good number?
What other single attack in PvP does 60 damage? Deathstrike can I suppose, if you track them, but there you have the "option" of not running.
Would a range from 40-60 be better?
Cap and range are not exclusive.

Cap just means the highest of a range.
I think 60 is about the max for a normal dragon, so making that a hard cap would take away the ability to complain about it.
But it is all a huge joke anyway.
A GD cannot catch you if you are running, even on foot unless you lag.
The 3spells regardless of distance thing has nothing to do with the dragons - it is a development screw up for ALL casting creatures and needs to be fixed.
So all of the complaints that give details include the commonality that the Tamer uses a bola to put them at a disadvantage.
Never realizing how stupid that sounds.. since tamers with GDs are ALWAYS dismounted!
And if they want to claim the tamer can be in mount-speed animal form, it will only prove they are just looking for a reason to cry. Tamers with a GD generally have well over 300 points in taming skills, and to give up another 99 for animal form to get mounts speed ... if you can't kill someone that only has 300 skill points in PvP, get the heck out of Felucca!
I will reiterate my previous comparison.
My tamer does not have defensive skills, just magery+bard/taming skills... and not enough music+peace to peace a GD.
I survive fully 50% of tame attempts on WILD GDs without using Honor (since it ran out weeks ago)
So if someone with 700+ points in offense/defense skills cannot survive against a GD with 50% of that power, they really need to reconsider their playstyle.
