Hello, new player. I rarely post on Reddit because it's so toxic and moderators seem so quick to delete posts, but I skimmed the rules and I think this is ok to post here. Sorry if it's in the wrong spot but I'd appreciate the advice of you stronger players. 

Been playing about a month. I didn't want to do ranked until I was ready. I maxed out 9 brawlers and did a little research on strategies and figured it was ok to try. I bumbled my wait to diamond 3 and fell just short of mythic before hitting a wall. 

My maxed brawlers (as indicated in the pic) are Shelly, Colt, Tick, Rico, Frank, Edgar, Larry & Lawrie, Byron, and Crow.

I have been having particular trouble in Brawl Ball and Hot Zone because my strategy that worked at lower levels is being easily thwarted by stronger players (I guess). 

Here's what I've been doing:

Brawl Ball--

Primary: Frank. I could be MVP scorer at low levels but now I am easily being beat down.

Alternate: Colt I guess...dps and try to knock down their wall. Rico 2nd alt. 

Ban: Bibi or Griff.

Hot Zone--

Primary: Frank again. My strategy is, call me crazy, to go in the f-ing hot zone, but it seems like I'm the only one on my team who goes in...my teammates just hang on the fringes and I get hyper focused on.

Alternate: Tick I guess. Larry 2nd alt.

Ban: Bo, Tick, Bibi

Heist:

Primary: Colt. 

Alternate: Edgar or Rico. Whatever's not banned.

Ban: Chuck, Nita, Edgar 

Gem grab--

Primary: Frank? I used to do Larry & Lawrie but felt so squishy so I've been trying to be the gem carrier with Frank...with mixed results.

Alternate: Larry & Lawrie, sometimes Edgar 

Ban: ??? Not sure so I usually ban Mortis or Edgar 

Knockout/Bounty--

Primary: Byron

Alternate: Crow or Tick. Crow used to be primary but I felt pretty weak until I got my special, which seemed to come too late or never.

Ban: Mortis, Edgar, Najia...just because I don't like playing against them.

Like I said, diamond level, so we're blind drafting...

Please don't humble brag about how you made Mythic or Legendary with one level 9 brawler. That's nice but I'm looking for constructive advice. Thanks in advance.

Am I doing this right? Please evaluate
