Seriously, it took us awhile to get used to blocking a lot earlier, attacking, walking and every action in this game with the lag. Then when we finally got over it you just had to add more stuff which misuse the lag, ending up in wasting revives.
I dont mind the new jelly spikes, but fix the lag spikes before going on with new stuff. If the base is not stable enough, whatever you add on top will just topple down like a unstable jenga tower
I never have lag other than the one caused by my own local network (for example when my brother uses his computer) so it's not a global game problem that affects everyone. If you live in the other side of the world, your IPS has you connected to poor routers, or anything like that, then it's not something that can just be "fixed" from one day to another.
