Mantid Elixir(Guardian) + Elixir of the Rapids(Battle) seem to be a much better alternative to Agility/stamina flasks if you can deal with the fact that the buff doesn't persist through death.
As an Alchemist with Mixology Mantid Elixir gives 2730 armour which is a 16~% increase in total armour for my brewmaster which can be coupled with the 990 haste elixir. Thoughts?
