Why do players use lifeline when they don't know her abilities?

I just had this chat with someone, I sometimes get Lifeline because I got up during the selection screen and didn't get Mirage. I don't usually use LL so forget about her revive etc. I have now started telling players that they have to yell at me to revive them. 

@Koochi-QIt's def very irritating when you get people who don't know how to play LL or BH. When I'm BH I'm scanning for enemies as often as possible & hitting survey beacons if I find any for at least the 1st 2 rounds. I'll get teammates that will never scan then we ambushed & die lol.

@scienceteacher74 This is probably the biggest reason why I associated myself with every legend. So that if the character I want gets picked or if the team looks off balance - i.e. too many picked the same type - I can pick another Legend & I'm comfortable using them.

@Lord_Scorpion34Another - point for you. I dislike the BH pickers who scan every chance they get (not saying you do this tho 😛). It was just like the buff that made BH suddenly relevant; the ‘moving scan‘. Suddenly random ppl picked BH who sucked playing with the character.

No one around, no footsteps, in the open scanning... WHY?! Its an open field! Even in a housing district where you can be sure nobody is they scan >.>

As a BH main you have to have ESP! You have to figure out where ppl may be and then scan. Thats how you become a BH that ppl in the begin feared. Now BH is just like LL. Too easy to use. Where old BH required skill & patience. Now it’s Scan McScannerson, become overheated and scan my files every couple seconds!

@Koochi-QWell I won't say I scan EVERY chance lol. But I do scan often. But I feel like I use it at the right times. I kinda miss the 360 scan. I wish u could choose between the 2, whether u want short-range 360 or the long range scan.

The others that irritate me are the LLs that solo rush or rush head 1st before the rest of the team just to get downed. Now we're down a person & a healer lol.

Because sometimes rez is just waste of time and just increases unnecessary damge for me

I get tired of stupid teammates especially with movement based hero end up KD'ed  in middle of open area 

@Lord_Scorpion34 I see how that's irritating but luckily i don't have that problem as i'm usually that LL.. 😃
