I have tried weapon stat on both high and low end of the spectrum, a high stat does not really make much difference outside of a couple outlier combinations. Sure, getting more damage however small is always welcome, but after the most recent adjustment, it now no longer has a TTK shift by itself on any weapon that I am aware of (which does not require a perk activation on the weapon). There were outlier combinations prior to the weapon stat, like PI 260 scouts or High Ground 390 pulses... High Ground was nerfed pretty hard, and while it now can still be a thing with the weapon stat bonuses, you never see it. 260 scouts can no longer 4 crit without PI and 390 cannot 2 burst without a buff (Elemental Honing for 1 weapon which if you ADS for too long, replaces your burst with a mini-rocket). In EoF Week 1, there were a whole slew of weapons which were juicy, but now fall just a bit too short. In addition, there are so many ways of gaining DR or overshields, that there would be ways to work around weapons which could just make that TTK shift if you built into it and with good movement, its hard to make that TTK because its an optimal. Without the weapon stat, now we have weapons which last season could be great against up to tier 8 or 9, but fall short on tier 10... and with everyone tier 10 now, a slight nudge in the weapon stat brings it back in line. This I feel was the intention for the weapon stat, not to make a flat shift in TTK for certain outlier weapons which only needed a nudge to shift the TTK (like 390 pulses, 180 HC and 260 scouts). Now, I feel that I should not build into the weapon stat much at all, but more build into health, super and class... but thats just my current feeling. If I can get a decent weapon stat once I have health, super and class where I want, then great... otherwise its less of a concern. Choosing weapons which are already strong rather than ones which need a bump from the weapon stat will make for a more cohesive build than one relying on a TTK shift by massively building into the weapon stat.
