Whenever I solo-queue, I run Rumble.
Rumble allows you to encounter a larger number of firefights against real opponents in a shorter time-frame than anywhere else.
Through Rumble matches, you’ll quickly gain map knowledge, and pick up tricks in the process.
Rumble places you under frequent pressure to perform to the best of your ability. It challenges you to win your 1v1 engagements, and control your fights so as to guard against being killed by a third party.
In Rumble, you can find other competitive players and build your network. Personal anecdote: Rumble is how I found Sinon Sawashiro. I messaged Sinon post-game, asking if Sinon had a regular Trials of Osiris team, and we soon became Trials partners.
A word on skill-based matchmaking (SBMM) in Rumble: it’ll both build your confidence and crush your ego. SBMM will pit you up against opponents who are ahead of the class in skill, as well as opponents who are struggling to keep a foothold. Every interaction in Rumble is an opportunity to prove to yourself whether you’ve learned from your previous Destiny experience.
Rumble is not without its shortcomings. Its scoring mechanics make it such that the top fragger might not take first place.
Joining a match in progress can be frustrating, because it means you’ll likely suffer multiple deaths to supers, but with the right moves, you might come out on top.
To earn the maximum Grimoire score possible from Rumble, you must win 100 Rumble matches. At my winrate, this takes just over 300 Rumble matches played.
To become good at Destiny, simply play 1000 Rumble matches.
