Since smiths are going to gain the ability to make chain armor, I think that the ability to make chain should be taken away from alchemists. But they should get another skill in place of it. I would think it would be nice to have a "summon potion buff skill" so it would allow alchys to summon a potion buff but Not in combat. I also think before it should give you slowness III for 10 seconds before(like when using recall) <--- Just to make sure it is not used in PvP
and it would have along cooldown around 20 minutes. The potion you could summon would be based on level. It would not be a potion but it would be the buff from the potion. It be a buff to stop people from selling them.
This is an example:
lvl 20 alchemist: Summon Potion of Swiftness(3 min)
lvl 25 alchemist: Summon Potion of strength(3 min)
lvl 30 alchemist: Summon a Haste buff(1 min)
lvl 35 alchemist: Summon Potion of healing I
lvl 40 alchemist: Summon potion of Swiftness II (1:30 min)
lvl 55 alchemist Summon Potion of healing II

This is an example:
lvl 20 alchemist: Summon Potion of Swiftness(3 min)
lvl 25 alchemist: Summon Potion of strength(3 min)
lvl 30 alchemist: Summon a Haste buff(1 min)
lvl 35 alchemist: Summon Potion of healing I
lvl 40 alchemist: Summon potion of Swiftness II (1:30 min)
lvl 55 alchemist Summon Potion of healing II
