Please try pushing Gladiator.
Everyone here is posting solo shuffle rating and asking 'am i Glad viable' and similar..
Please do not discourage yourself by getting answers like 'Nah man ' or ' You gotta be at least 2.7+ for Glad'. Ive seen 2.7+ people struggling 2k-2.1 cr 3s and Ive also seen and know people that cant push more than 2.3 Solo getting Gladiator... People work differently and sometimes you will be worse at adapting constantly in Solo shuffle environment than actually playing Organized 3v3. The only thing at this point that is stoping most players achieving Gladiator is finding 2 more people .
Ive been stuck as a fury warrior ( i refuse to play arms) for month and a half before finding 2 nice individuals that were also good players and we achieved gladiator in 5-6 sessions.
Keep LFGing until it clicks and then just try and setup future dates for 3s so you can build synergy and discuss tacts u wanna use vs teams.
Also try looking at Non Glad/Legends players more , there are some hidden gems in Duelist/Elite exp players.
