I used to save on improved eq thinkin' the demount cost is kinda much at 200 bonds. I've changed my mind.
1. bonds are plenty with battlepass/daily missions/etc.
2. with eq 2.0 you can really use them and keep the special slot for something else. I.e. - charioteer(on this I have bounty, not improved) - bounty irm in a random slot, std gun rammer in first slot. Probably on tds there's the biggest gain from bounty/improved eq in 2.0.
out of the improved eq, vstab is obvious, rammer is very good(see above - you can place an irm instead of rammer in 1st slot on tds). Rest are debatable(never been a fan of vents).
t34 shielded... I have it from some marathon. Never played it. Question is: why would you buy a t5 premium? Won't ever make credits. You want credits, you play t8 premiums. Also, why would you buy a tank with a not so stellar reputation?
oh, and yes, kpz 50t won't make credits, but if you grind ranked, it's one of the best t9 meds.
