you see I can survive those on SCH too with PDT gear and stoneskin. The problem is, until you actually are able to reach out to your melees to cure them (because you need to save yourself first) they will most likely be dead. If those AoE would be only 15' instead of 30', ADL would be managable without PD. The problem is if your support dies, your front line will eat dirt too.
The problem is due to largely enhanced AoE range of ADL, mages cant stand anywhere safe + be in cureing range, because his AoE exeeds 21'
