I really like the Recon class — it’s actually the second class I play the most. Overall, I think its gadgets are well balanced and allow for different playstyles. You can go long-range sniper, or switch to a more aggressive recon role in close combat.
The spotting capabilities provided by Recon gadgets can make a huge difference during fights or when pushing/defending an objective.
When I play long range, I usually run a sniper rifle with the laser designator and claymores. It allows me to support my team by spotting vehicles and locking down flanks.
When I play more aggressively, I prefer using DMRs or carbines, along with the drone and C4. This setup gives me good versatility for close-quarters combat while still contributing with intel.
The only thing I find a bit disappointing with Recon is the lack of binoculars as a gadget option. I think it would be extremely useful and much more discreet than using the laser designator, especially for pure reconnaissance and target identification without revealing your position too much.
