Demolitions Specialist (Saboteur) and Smoke Mine

First of all thanks for the recent buff (100% mine arming speed) so now there is actually a reason to play Saboteur mine.
Now Smoke Mine is a very good movement skill for mine player both in boss fight and during map run, but there is 1 problem within Demotilions Specialist node that is a downside to this playstyle. In boss fight the best strategy is lay Smoke Mine first then move to other direction then stack up 3 time mines(normally 9 mines). The problem is with 10 maximum Mines we can control this (1 Smoke Mine + 9 damage mines) but with "20% chance to place an additional mine" there is a huge chance that will destroy the first Smoke Mine and then boss can catch us.
I sugess: make Smoke Mine doesn't count toward maximum Mines or/and change the node to something that actually buff to mine play style ( with Minefield support I don't think we need 20% chance to have 33% more damage ,I rather know how many mines I placed instead of a chance that can destroy my first strategically placed mine ).If you're gonna change the "20% chance to place an additional mine" , here is some sugesstions:

-Increased 30% movement speed if you detonated mine recently
-Mine damage penetrates 10% elemental resistance
-Can have up to 3 additional Remote Mine placed at a time
-50% reduced Mana cost for Mines
Or something special that change the mechanic instead of buff some number like Chain Reaction from trap:
-Mine can be detonated an additional time
-Mine can be auto detonated when destroyed

20% chance to place an additional mine really cramps my style as well. Unless you are mine-spamming with detonate mines totem, it's mostly a debuff rather than a buff.
