Active Cond removal
The first major difference between the Mesmer and the ranger is the armor. Most heavy conditions classes are light armored. If you have the abilitie to stunlock them, what you can have as a ranger with shortbow/longbow, you can easily burst them down and prevent them to use to much of their conditions. In combination with for example signet of stone(and the right traits) you have the possibility to ignore all the damage for 6sec + Troll Unguent(which is a high regeneration skill) you normally can compeet with heavy condi classes.
Using TU i tend to lean on evasive purity so that poison does’nt mess up its potential heal Because i know a dodge removes it. 10 points more in the same trait and get Nature’s voice, bring Guard with 10 in BM for 20% off cooldown, add in soldier runes to remove condition on shout and you get a recipe for 12 sec on demand condition removal with the bonus perma regen/swiftness.
Pure awesome.
