As a fellow wiper player, I’ve found it pretty easy to get into tri and naut when branching out. However depending on how (and why) you play wiper, these might not be your best choices.
For example: The reason I like playing wiper is because it has a lot of range and chip damage, so it can screw over certain weapons in 1v1s (think brellas, short range shooters), and it also has the ability to keep up with those same weapons because of how fast it moves. Those traits are why I enjoyed naut and tri, since they both share parts of what I like in wiper.
But if you play wiper like a pest, then you’d probably like tetras and squelchers more, since in those weapons the main commonality is speed over damage and/or range.
