What are the RTS games that you have played with the worst lags and connectivity issues? How were you able to find solution to fixing the problem or did it ended up making you to quit playing that particular RTS game? Total War: Rome II (2013) nearly had me frustrated when it launched with its severe lag, long load times, and frequent crashes.

Which RTS games had the worst lags and connectivity issues?

I think Command & Conquer 4: Tiberian Twilight has frequent lag and connectivity issues. I will also include Warcraft III: Reforged in this list. This game got a lot of backlash due to poor online performance, including lag and desync issues during multiplayer. Another game with connectivity problems is Age of Empires Online.
