If I got 4 indon teammates, I will not accept the matchmaking. They hate malaysian flag and will blame me for the whole game if loosing.

To rank up solo you need to buy good solo hero. The game not really balanced, some hero too op some hero are useless. Buy hero with high win rate. Check youtube which hero to buy.

I tried AOV and the game feel too long to my liking. I just played ML for 3 month, will tried AOV again once bored with ML.

that's why playing with friends/guild members are preferred. hopefully meet noob opponents.
AOV guild slots can be expanded, by "compressing" wallets
some malaysians use other country flags too

I find playing solo rank at lower level mcm best...less toxic player & most team mates give cooperation, janji menang.
