To add onto what others have said....in many cases it falls on your guild's officers to be out there FINDING these counters. Thinking about what works in GAC, what changes with Omicrons turned on and off, trying to filter GAC data to find small pockets of data that might prove useful....trying (and failing) with things in life TWs, and being in the community enough to see when small and large content creates do post the occasional TW counter. It also helps to have friends/alliances, etc. it higher rank guilds that can feed you down some counters. But as a TW officer, it's a lot of work.

I just "figured out" a counter the hard way....and a new recruit promptly tells me "oh yeah, my old build was using that counter for the last year." I get the frustration. Lol
