High. My name is Kommisar and I am a Brawler. Mind you, my ideal brawl range is about 300m... but I digress.
It's a different skills set. And, to be a good brawler, it IS a skill set. This reminds me of all the 16 year old basement "martial arts experts" I've met over the years. Telling me that, for example, the Katana was the ultimate melee weapon and kendo the ultimate technique over all others. Because, yea, you know, a kid living with his parents is the go to guy for opinions on sword fighting.
I'll be honest, right now the game does favor brawler builds and pilots to an extent. The maps are on the small side. And ECM limits the use of LRMs unless you have a solid team supporting them. There are no Area Effect weapons that would discourage tight groupings. It doesn't mean that snipers, support or other tactics can't and don't work; just that the game, as it stands now, does not have many draw backs against a brawler. This will change as the game develops.
OH, and there are instances where running up and hugging a mech is a great tactical move and not just dumb play! If the enemy mech has mostly PPCs or LRMs... go hug him. If you are taking lots of fire from multiple mechs, go get in close with one and make their sight picture more complicated. I've actually had enemy mechs save my bacon this way by crippling or destroying their friend with FF in their haste to kill me.
