1) Deathmatch - Feels like the most balanced of them all and you get to have a lot of fun killing other players. Only when matchmaking rating starts to go higher do you start to see cancerous things like unkillable crossheal groups that never have a reason to separate but they're not as bad now that BGs are solo queue only.
2) Crazy King - Although you can get some flag trolls or unlucky moments where your attempts to capture gets halted by being overwhelmed, the exchange rates of the flags means you'll usually get some decent teamfights going on on the capture points.
3) Chaosball - Nice and fun carnage if both teams stack on ball. Not so fun when an immortal speed tank runs around in circles around the map and ends the game with 400 point difference to 2nd place team
4) Domination - I don't like this game mode because the most efficient way to win is to not to interact with enemy team, but to keep circling between the flags while you can go afk and go drink some tea.
5) Capture the Flag - where to begin? The game can end up in hostage situation where each team is holding an opposing team's relic. Overall, it feels like there are too many things you cannot control. When going to capture a relic, at least one of the following is very likely to happen: You attempt to capture a relic, your defending (or worse, absent) teammate dies and enemy team captures ours - You attempt to capture a relic, you notice there are too many players by relic. You must retreat - You try to capture the relic, an enemy respawns on top of you and you die - you attempt to defend the relic. Nobody comes so you'll just die of boredom instead - You attempt to defend the relic - you get overwhelmed by the enemy team. You can buy some time but you'll eventually run out of resources so that you die or are unable to bash the one about to carry your relic. And your team is nowhere to be seen doing anything useful, or if they do, the game ends up in hostage situation as your team's relic carrier is unable to claim the relic.
Overall, just too many bad situations that can happen too often with capture the relic that are unfun to experience.
death match and chaos ball are my favorites...i also enjoy domination / crazy king tough
the only one i hate with a passion is relic hunt...i really don't like it, i am horrible at that one... unfortunately in the same category as chaos ball...
