i would agree, only one server where i saw a lot of techs was SGR Vs Villians like 2 servers ago, a source of Multiple 1Mill + WWKs..
But com has been a relatively quiet non tech server.. No thanks to Duat and IKEA to drag that in this server
You are wrong if you think techs hasn't been used regularly on COM servers before. Might have been stealthier since TG didnt "officially legalize" techs until recently (and it seems like most com players try to call it other things or hide the usage), but I have played various servers here since around 2012-2013 and I have never been in a large alliance that hasn't used techs. I didn't start to think about using it myself until I realized its potential on a com3 back in like... 2015? and have seen techs on pretty much every large server on this domain since then.
Just because many of the players on this server hasn't done it personally or known what to look for before it was talked about more doesn't mean it hasn't been here since forever. The last year or two it has just been made clear that techs doesn't break the rules which has made a whole lot of more people use it.
Not saying that IKEA and Duat didn't help it expand even more this server, they probably did. But it is hardly like COM has been some sort of safe haven for tech free users the last 5 or 6 years either if you actually check the top accounts on the most competitive servers
