RE: LO
If you are willing, I'd like to get your help to create a number of QoT Balance mods. I think there are lots of different ways to go with it, so variety is (in my opinion) the way to go.
RE: LO RE: Compost
You are mostly correct. The one caveat I have to add is that she would not gain the additional health from the Compost Boost. It would only increase her maxhealth, not her current health. That being said your sigil observation is correct, and intended.
Level 10 QoT (standard load out as specified above) with 4695 Health, 4695 MaxHealth, and 19 Health Regen
With Max Compost (3 ranks + 3 levels from kills), 4695 Health, 7695 MaxHealth, and 79 Health Regen.
With Sigil (+50% health) 8542 Health, 11542 MaxHealth, and 79 Health Regen.
With Priest (reinforcement Heal) or Monk 10%, 1154 Heal per 8 seconds
With Priest (reinforcement Heal and Healing Wind) or Bishop 15%, 1731 Health per 8 seconds.
With Shield IV 1450 every 7 seconds
With Mulch Shambler 1500 every 7 seconds
Of course, this build is 1 Summon Shambler, 1 Mulch Shambler, 3 Compost, 4 Bramble Shield, which uses up 9 points. Which leaves you with no real damage abilities. You'll only get auto attack and minions.
Sure she has health at the level of a citadel for 30 seconds, but she also only does the damage of a citadel.
RE: Ground Spikes
It has a .5 cast time which is useful for an interrupt. I could see swapping it for a slow effect without much problem.
She will suffer a damage loss when converting from removing Armor to +% damage. However, I think that it will make things less expert biased and more friendly to team play. I think that negative armor was an oversight on the GPG and wasn't intended.
RE: Spike Wave
I don't like the idea of Spike wave as an interrupt. It has a relatively short cast time of .4, but it still has to travel towards the target. It feels a lot slower than boulder roll. There should, however, be reason to purchase the higher levels of Spike Wave. Adding on increasing stun length in addition to an increase in slow duration sounds reasonable.
