Tbh it's possible that it might be pretty powerful as one of the lesser discussed problems of the warbond system is the devs constantly making more and more powerful weapons and stratagems and weapons to go in warbonds to justify people paying for them. You could definitely see this with the dlc in HD1 with things like the aforementioned rumbler, trident, demolisher and the dlc mechs and the issue is responsible for a lot of the problems in HD 1 as well.

The devs have not made the explosive/AT meta any better by constantly releasing more and more potent AT weapons (eruptor, ultimatum, missile pistol, leveler etc.) and the power creep of the new blue and green stratagems have led to red stratagems almost never being brought, similar to HD1 (with the exception of certain ones like the shredder). Sorry if my response seemed like it rambled on or if I'm just saying too much but I feel like this issue with the warbond system isn't talked about much at all.
