1.9 involves more skill based PvP, than luck and spam based PvP. (
@Tactic_Gaming said "So many players hate 1.9 PvP", Which is COMPLETELY NOT TRUE in my opinion. I see more people playing 1.9+ than 1.8).
If 1.8 gamemodes were added, then people would try it out, maybe like it, therefore having less people on the 1.9+ client, meaning 1.9+ would slowly die out on cubecraft.
Plus, some of the maps for different gamemodes include blocks that are 1.9+, so the maps would have to be edited or not used in 1.8 ( reffering back to the part before this, 1.8 becoming more popular than 1.9+), so what if that was someones favorite map with 1.9+ blocks?
They would not be able to play there favorite map in 1.8 unless edited.
You also said people play on other servers because CubeCraft (the best server ever), doesnt support all of there gamemodes in 1.8.
I personnaly find this wrong, you can play Skywars, Eggwars, and (PvP but on a 1.9+ client).
Its not all of the gamemodes, but its the most popular ones i think.
And if people play on other servers just for the sake of 1.8, and finding the other servers fun, then why would they comeback to Cubecraft?
You ALSO mentioned this would bring back the servers popularity, theres only one problem.
This would only bring back popularity to the 1.8 gamemodes, like i said, ruining 1.9+ on cubecraft.
Also, (This is my point, not basing it off of your comment), i like 1.9+ because of the different blocks they get to make maps out of, in 1.8 you cant make the maps you can, because you dont have as much block choice as you do 1.9+.
Yeah, to wrap this up, i still question why people enjoy just spamming a button and killing players in an instant (assuming they dont have a god apple), and not having decent well fought fights, as you can in 1.9. The 1.9 PvP gives you more oppurtunities to have better fights. Also its not just "Hit Sanik Fast", there is strategy involved also, rather than just hitting.
Block choice. You get a more variety of block choice in 1.9+ rather than in 1.8, giving more oppurtunities with maps than in 1.8.
Joining other servers for 1.8 PvP. Getting on another server for 1.8 is fine. This would make one of Cubecrafts players not be on Cubecraft anymore because they would find the other server to be more fun.
Popularity on Cubecraft. Adding 1.8 gamemodes would only make Cubecraft popular for 1.8. When 1.9+ is the most popular client on Cubecraft right now.
This took me 20 minutes to write, but hopefully i could help!
