I have mained nami for 3 seasons and love her but I gotta say Braum is a much easier champ to peel with and ultimately help carry. He just fits the meta so easily.
Nah. I can't peel worth a thing with reactive-style champs. I remember the time I tried playing Zilean and kept messing up every single ult (either too early and it timed out before my target died, or too late and they were already dead before I got to cast it). Dictating fights myself is the reason I'm so comfortable with Nami, since I get to go in, even at level 1 with my W, level 2 I can poke with a couple E autos and then W, and starting at level 3 I can threaten some pretty nasty cc chains with E plus Q, or use my bubble to peel/disengage. I know her play patterns and the amount of abuse I can take back in trades pretty much by heart by now, which allows me to make way better plays than with any other champion.
The meta's also all kinds of messed up in my division, since I still routinely see low-tier champions all over the place. The lethality items everybody's using do sting as a squishy mage support that doesn't build armor, but I'm still doing okay against them for the most part.
Watching diamond/challenger support games are very helpful. I only watch the players who talk though. Makes it more entertaining
I like it especially when they tend to speak out loud about what they're doing at any given time, since it's easier to comprehend just what drives them to do things in a certain way than when you're just watching them do stuff. For example, them saying "I usually build <Item A>, but this champion requires me to go <Item B> first for <reason>" is a lot better than seeing them just rush Item B instead of what I expected them to build.
It's not a bad idea. Playing someone you don't want in the middle of your team is a good counter. Other than that, you can also play around the minion wave and force him to take the hook in the middle of your minions.
Personally, I see Blitz match-ups as a nice opportunity to test my skillshot-dodging abilities. Playing Nami into him I can easily make his life hell by constantly poking him while dancing around my minions, but if I
had to go melee then I'd probably pick Naut as well. Most of the time it'll be giving you a free flash into the enemy adc by hooking you, since you'll still get to keep your Q, R and flash to get to them while shrugging most of the damage off with your W.
