Hello forums as mentioned in the title , I am a new player for this game and even to the forums. So it would be very generous of you guys if you help me in my journey.
So this was my Day 1 and I had been prepared a little before starting the game. I had saw some videos of guides and gameplays in YouTube to help me out. So I completed act 1 today. And this is my roster.

So here are my set of questions, I want to ask you guys.
1]How is my progression on Day 1 ?
2]Who should I rank up?? Or should I wait for some more champs
3] I have read about variants and about mastery build up, so I can't see variant in my game. Is there any specific level to unlock variants??
4] What should be my next aim??
5] How can I change my profile pic in the forums??
Thankyou in advance. I would be posting more queries , so please look out for any new messages in this post. Once again thank you for your support guys.
