OK. So you held the MRanger off long enough to force them to reset. You didn't die, and they didn't kill you. If you're in open world, you aren't obligated to stick around and wait on them to recover. Or call a friend to come in and jump them. If you're playing in a BF or fighting over a specific location, congrats. You've taken them out of the fight for a while, and a Ranger stealthing around recovering isn't contributing to the rest of the match.
As to the Ranger's stats, that is not an accurate comparison. For instance, between MCarb and MRanger, let's break it down.
MRanger gets the following from their class alone (assuming I counted correctly):
- Anti-Personnel Traps: 100
- Burst Run Efficiency: 45
- Camouflage: 100
- Detect Camouflage: 100
- General Melee Accuracy: 50
- General Melee Speed: 22
- General Ranged Accuracy: 60
- General Ranged Speed: 25
- Melee Defense: 95
- Ranged Defense: 75
- Tactical Expertise: 100
- Terrain Negotiation: 55
That's 827 stats from the class, 500 of which are either trap, camo, or mobility related. Only 327 points of direct combat stats. These are spread across both melee and ranged, meaning most players will only benefit from roughly half of the stats for accuracy or speed. That's roughly minus another 70 stats, so roughly 250-ish of actually relevant stats from the class.
Now let's do MCarb.
- Carbine Speed: 30
- Carbine Accuracy: 15
- Carbine Accuracy While Standing: 50
- Carbine Defense: 30
- General Ranged Speed: 20
- General Ranged Accuracy: 75
- Melee Defense: 10
- Ranged Defense: 10
- Healing Potency: 8
Total stat points: 248, all of which are usable at all times, and all of which are direct combat stats. Almost the exact same total as MRanger, but more combat effective as it's more biased towards offense than it is defense. Meanwhile while you both can bolster the area you're missing with another class, the MCarb is still coming out ahead because they're getting so much more effective skills to use than the MRanger is for single target and more flexible AOE.
Again this all sounds like people choosing to play into the Ranger's strengths and not utilize their own classes strengths against the Ranger's weaknesses.
