I neglected healers till recently. I'm a maxed th9. Working on heroes, so I only care about DE. Without heroes to aid the attack I need a force to sustain itself for a longer time. Started in the 1700 cup range (currently about 2050 cups) and have attacked hourly with a giant/healer combo. So in that time I can generate 2 heal spells. I try to avoid heal spells due to the cost but often use 1. Only attacking th8 to mid-level th9s and rushed th10s. Haven't failed to get a de storage yet in about 70 attacks. Use the heal spells as backup. Averaging about 1250 de a raid. Not seeing a whole lot of decently filled DE storages that aren't protected by infernos that i've haven't attacked. Most folks have skull wall or weaker. I figure when I get up to upper c3-c2 I'll switch to loonion. But I've seen no reason to change now. Really isn't many juicy full de storages in this range. Only playing casually so I prefer to keep the nexting under 50. Both heroes are upgrading (to level 13 and 11) so it has produced the de required. One of the things I'm trying to do though is to get to a higher cup range so the de is more plentiful. Kind of space still. Was settling for 8-900 de in the 1700-1850 range. Once I got near 1900 cups, 1000+ de has been easier to find.
I couldn't imagine using giant/healer if I was hardcore farming though. As a casual farm it's been quite nice.
