You are talking about the GDI that is server-specific to express and primary.
Your suggestion makes topfeeding as a non-GDI against GDI targets immensely lucurative tho. That is a big problem in Primary and sometimes in express as well.
Its an imperfect GDI to counter imperfect players who used to ruin those servers. I have plenty of netting resets in primary in e2025 and never once when I was not massively suicided by someone I never even touched, lategame after 40+ days.
In express the first set I netgained after my hiatus I was about to win with a theo casher but I forgot GDI and bam I was reminded why I stopped playing this game all these years ago: https://www.eestats.com/express/oldcountry/1287/6
Set after I remembered GDI: https://www.eestats.com/express/oldcountry/1292/2
And the two sets after that and all sets I wanted to go for the win: https://www.eestats.com/express/oldcountry/1298/1
I do see that the lack of troop and tank demand among players hurts the market, and I do think that it would be nice to fix that to potentiate real TTRs and TMBR resellers (no just jumpers). But your suggestion doesnt really do that.
