Would be too long an analysis to include all the possible options, it as always depends on what you want to do: offense/Defense/event/Titan/Tower whatnot
One thing though: Equalizer is already the worst of all war effects and just got so much worse than it was already. That completely idiotic elf will now kill all 5 enemies, not just like Erlang 3 targets.
