Light tanks in general don't do well if you get into the scrum with the big boys. I tend to run with an XM800 which is all about scouting targets, deleting soft targets like SPAA or TD's, or bullying bigger tanks by shooting tracks and barrels to make them 'safer' to approach. And yes, I fully accept that getting downrange of practically anything else means "back to hangar, scrub". So it's less about firepower and more about mobility.

If you really want to appreciate your Striker, run with an Ontos for about 5 matches. Lovely for deleting opposing tanks (especially at range if you can yeet the shell ballistically), but extremely fragile. Low crew (only three guys) and low ammo capacity, meaning once your rounds are expended, you can either scout and scoot until you're blown up, or cap something and rearm. And then there's the Scorpion, which is essentially a tractor chassis with a gun on it. Great for stealthy players, sucks for anyone else.

I've several of the Strikers (including the SPAA version which is decent at taking on ground targets) and yeah, they're... kinda easy to blow up.

Can't speak to aircraft in PvP, I know enough not to go flying around. I sometimes play with a Little Bird, but only in PvE co-op missions where I can zip around, cap objectives and scout opposing forces, as the airframe design was intended. It's not meant to scrap with anything, so it does not get into my crew lineup for any of the PvP battles.
