Before 2019, do not have GBG in mobile, and no chance for GvG in mobile till today. Those were the times, Game is played for entertainment purpose and not for guild rules. Can bet like, after GBG, lot of guild update their guild joining rules, (only to me, I guess) which is kind of abuse but mentioned as rules like accepting the contract to follow some criteria.
Those golden days coming back means ready to spend 15000 diamonds if they allow me to play without GBG and GvG (where GvG already ruled out for me because of mobile). As a fact, already enjoyed those moment in the game. If it happens, will become more happy but my guild mates will be sad for sure.
Because of them, can sacrifice my desire on the game to play like that and continued to follow rules for the guild.
If no GBG or GvG, Still more battles are there like events quest, challenge quests, pvp, neighbor plunder, continent map and GE. Never wanted GBG, but game forced us to do it in the form of Guild rules indirectly. IMO, doing battle itself negative mind set, but to run a empire, handshaking with the opponents in the means of softlocks for checkers to make sector reservation is really not good approach, whereas it is the only way to make sure everyone gets rewards.
