Got into a discussion with a clan member about tyrants and C grade. Basically he said that since tyrants have lousy dodge and don't really need the speed in C grade they should use Heavy armor, my way of seeing it was that since they do get light masteries, it would otweigh the extra armor you would get from heavy.
That Plated Leather is expensive for 12 lvls that go by fast isn't really a concern cause reselling value stays high...I don't see that as a valid arguement.
With more STR, more VR effect, so more HP regen, so less problem with lower P def from light armour as well.
Well alot better than what i got on my tyrant =) Was able to get Theca set by giving a clan member my Composite Armor (he bought the theca set for 1,6M) and then i switched my Katana into a knuckle duster. Hopefully by the time i reach 40 on my tyrant (9 lvls to go) i will have Fist Blades with haste SA =)
Do not forget that light armor offers much more evasion than heavy. This means that for every hit you avoid, you compensate for 3-5 hits that you would get if you wore heavy. Additionaly there are passives for light. You get Agile movement (accuracy and speed increase) that is associated with light armor. So I would strongly not advise you to use any other than light armor. Plated leather is the best armor set for c (and maybe b-grade). But if you can't afford it, I would recomend a tempered mithril set (evasion +4) as an alternative.
