Buff Bloodhound, Mirage, Octane and Crypto

I also agree that Bloodhound and Crypto are not as weak as Octane and Mirage but Bloodhound, Crypto in comparison to Wraith, Pathfinder, Gibraltar are still weak and are need of some buff.

Octane's stim takes away alot of health from him, if the stim would cost less health or the swift mend could regenerate Octane's health faster it could really help. Also jump pad being not so effective ultimate should come more often

Bloodhound's tactical is his only weak spot, the tactical should scan for a larger area and the results for the scan should stay longer. His tactical and ultimate also makes heaps of sound which can give away his position the sound should be lowered down

Crypto is in a nice spot, the only buff he requires according to me is there should be an option for his drone to hower above his head and follow him.

Mirage is according to me the weakest legend out of all he should get a complete re-work as his passive is real weak. His decoys are easy to identify and his ultimate can be easily countered by hearing for the foot steps.

I agree with the OP. Although I think out of the four legends he has mentioned, Octane is probably in the best spot.

Here are some basic ideas on how to buff them:

Octane: Either do something with the jump pad (like give speed buff to the teammates when they use it), or make it so he doesn't loose health when boosting. That's about it.

Crypto: Greatly reduced drone sound, and add some sort of follow mode, so you are getting benefits of extra info about enemies while still been combat capable.

Mirage: Decrease cool down time on his abilities greatly. Make the clones look and act like the player, as in hold the gun like a player, and actually give them basic AI so they can jump, slide and climb over a wall. Maybe add another passive perk that creates a clone of mirage automatically whenever he takes damage with cool down of like 3 minutes or so. Mirages everywhere!

Bloodhound: Reduce or completely take away the sound when he activates his ultimate, and also while he is using ultimate allow him to climb walls just like Revenant.

These are pretty generic and can be refined further, but at least they are a good start to get those legends to somewhat competitive level with the rest of the beasts we got atm. 

I think lifeline could use a small buff as well tbh, maybe just have her drone heal slightly faster or option to pick it up and run while it’s healing you but you can’t use weapons or something of that nature. Or buff the quality of items in her care package? Her care package has become more of a liability than perk mid to late game

Bloodhound did get a slight buff, and it helps a bit. Octane could use a slight buff, but hes playable now. Crypto got a slight buff and he was already viable. Mirage could use a buff, but if you play to any of these guys strengths and use their skills with your team they are viable. Maybe not at the highest levels, but I doubt you are playing at those levels anyway.

I concider lifeline one of the best. My most played just because  pathfinder became so populare when they shrunk hos hitbox back in the day.
