Well, ENT Connect doesn't necessarily decrease your ping, it just helps to prevent you from dropping in the case that you lag out. If you team ends up kicking you, even if you have ENT Connect drop protection, that isn't going to help.
My suggestion would be to call your ISP and ask them to improve your connection to the United States (not sure where you live, assuming outside the US) specifically Atlanta, Georgia where our servers are hosted.
You can also run a tracert on atl.entgaming.net (How to run a tracert:
