Why Artificer matters in the Rogue Mechanic tree?
What are Artificer talents?
Suggestion:
Consider making auto-disable option in Rogue Mechanic tree (probably Tier 4).
For example:
1) search (or auto-search) trap box first
2) 1 sec timer
3) then auto-disable (with some penalty, so yes, it can explode)
4) that's why auto-disable option should be made as toggle
