Your secret weapon for Ranked?
We all have champions that we main in Ranked ... for example, I play 
constantly and spam her whenever I can. I also play 
depending on the match up. However, if I know the match is going to be rough for any of my selected supports ... I pull out my secret weapon. I give you, Nami.

She's a special kind of support because her kit syncs well with almost any ADC. Her W is great for harassing people, but also healing your allies. Her bubble is an easy AOE stun to pull off, and can usually get 2 or so people if you time it right. Her E is probably the bread & butter in her kit, because using it on an ally allows them to slow someone for 35% for 1 second and deal 85 (plus 20% AP) damage for three autos. Then you have her ultimate which is a tsunami ... one that takes up half the lane and travels quite far. Those knocked up by it are slowed, plus the wave allows your allies to run faster.
She may not be tanky like my main , may not give immense heals like , doesn't dish out insane damage like does, but 
to me is the kind of support that's special because she can be the jack of all trades, without needing to specialize in one role. Want your ADC to have sustain? Her W with items like 
can really keep them alive during harsh ganks / team fights. Her CC is balanced enough to keep champions like 
at bay (unless they avoid it of course). Her E makes an ADC like 
an absolute monster, one you will likely lose trades with while she has E's blessing on her. Most importantly, her ult can be a game changer to stop assaults from champions like 
, ect. during their animations.
TL;DR Version: My secret weapon is because she fills in everything an ADC needs in a Support. Heals, CC, grants stronger autos for you, and an ult to stop assassins or champions from reaching you. With the right items, she can keep you alive in most situations, give you the peel needed to out trade enemies, and most importantly she's someone I rarely die with (2 - 4 deaths a game, hardly ever goes beyond that).
Question: What's your secret weapon? It doesn't have to be someone you main, or it could be- but this champion is the one who'll pull you through hard matches and bring you out on top. Although I main Leona, Nami can do so much more even though she's not as tanky.
no1 expects the burst and hes not seen enough to understand his kill potential/range.
delete the carry win the game
Level 3 = First 3 Abilities = Easy First Blood
Trying to back under your tower? Itd be a shame if a random nuke launched at you
Easy Farm, Easy Life
those who read my posts know that this isnt that big of a secret weapon, but when i queue up fill and get mid everyone cries.
I'm silver.
She's very good at punishing players that get caught out, which happens a ton in my elo.
She can 1v1 most champions early, putting her in a great position to harass the enemy jungler and fight over objectives.
She has very strong early ganks, whch allows her to snowball the game before team members have the opportunity to throw; or alternatively, to turn around a losing game in our favor.
She has just enough mobility to catch out mispositioned carries in teamfights.
She has a well-rounded kit that works in nearly any team comp. She has good burst, hard cc, and can be built fairly tanky to boot.
The only real problem here is that she falls off late, but honestly, I've found the best strategy for carrying at this elo to be snowballing and closing out the game before your team has the opportunity to throw. She's really, really good at that.
