[Request] Maelstrom Arena Helper

[mikra]

I'm looking for a addon, that gives a little help for (veteran) Maelstrom Arena.
Like notifications and explanations for mechanics, attacks, spawning mobs and so on.
(Maybe it could also point to critical mobs, like the webspinners and venomous horvars in stage 6.)
Something like a spezialized RaidNotifier.

The high difficulty of that arena would really make a helper addon very useful.
