After three weeks of spamming the same hero over and over again on my ranked matches, I have finally reached 'Expert' level on the tank/regen hero Uranus. There are still 2 tasks left though for the Mastery Book to be completed but as for the expert level goes it is now at max level. XD
After Uranus, I'm thinking of maxing the support hero 'Angela' but not on ranked matches anymore but only on classic matches. Truth be told, the game is now starting to get boring for me as it is heavily reliant on the teammates/opponents you get on matches.
Most of my loses are because of teammates who have unstable connections and therefore can't play really well. Most of my wins too I believe are for the same reason. Point is there's too many players who play under unstable connection on this game that it's starting to get annoying especially when playing under ranked matches and 'stars' are at stake. XD
