"TEAM DUEL"

Since each turn lasts 2 minutes, and the players aren't exactly taking their time...

Playing with a 2-minute turn time will never improve your gameplay; this is evident from your posts!

Even now, when I defeat 119 undead with 24 archers, it doesn't take much time...

24 archers can defeat even 1000+ undead. This isn't an indicator of good gameplay! You need to learn how to build effective chains of units, and you can't do that in 2 minutes!
