how often can a engineer moa you?
Base CD is 120 sec, see here:

There are two traits with cd reduction, 20% and 15%:

HGH is pretty standard, however you won’t find many Engis running tools, since alchemy and inventions are more important for the standard scrapper spec.
The AoE Moa is quite useful in some situations (for example to prevent an attempted res before it starts), but in most cases you can just counter it by using the moa skill 5 to evade and leap out of pressure at the same time and (if neccessary) an additional dodge, since the duration is rather low.

Transform enemy team to moa twice in a row!
Just HGH puts it at a 96s cd, but HGH + Tools puts it at 78s. If they’re running tools and elixir x though, chances are they’re running the kinetic battery trait as well, which technically lets them use it every 40s, but more realistically means they can use it twice within 10s with the usual 78s cd. If you find yourself getting moa’d by the same engi twice in a row or twice in under a minute, you should probably focus them as they’re probably not running scrapper (and thus have next to no sustain).
