You obviously missed the point that a single scout dualist with the 1911 can pretty much 2nd a pred by themselves, or Dutch 87, assault deadly, or recon sniper, etc. FT damage capacity is insane and everyone knows this but apparently not you.
FT also has the capability to ignore the preds stealth through the spotting mechanic, motion trackers, UAV, ACIG, just listening to the preds elephant sized feet. FT can also hit the pred from multiple different angles in which the pred can’t retaliate because they cannot go after more than person at a time unless they’re hugging each other. FT can also mud up and completely negate target iso and thermal.
Also In order to insta down anyone you have to use the correct specializations and weapon I.e disc with elder stalker and down range and then again that takes work since you’re left vulnerable.
Fact is:
It’s very easy to win against potatoes but against good teams pred will struggle and more often than not lose and by the way you’re talking you only fight potatoes.
