Both of these characters got reworked because they were meme picks and had low pick rates. Now they are more generic, still not viable but less fun.
The upgrading mechanic on torb was fun and it’s really sad that level 3 turret doesn’t exist in any capacity anymore. I like his current ultimate but his overloading ability is just a generic temporary speed and health boost to make him “viable”. I’d trade that for some cool turret upgrading any day.
Sym has always been kinda a mess but I wish they kept her as a support instead of a dps nobody ever plays. Her old teleport was awesome utility. Currently it requires a key to use so nobody uses it. Current syms ultimate is basically a support ultimate anyways lets be honest.
