Well we're royally screwed (EP3 SPOILERS)
 

Not only have we lost two of the better shooters (Carly & Lilly) and a medic (Kat) but now we're left with a depressed man, alcoholic hobo, kid that can't shoot, a twitchy teenager and two strangers I wouldn't trust a mile away!

Lee, we're royally fucked!

In Kenny's defense, though he is obviously upset, the trailer for episode 4 shows him yelling (as he always does) and saying he is sticking to his plan... Depressed or not, Kenny still seems useful.

I wouldn't consider pig headedness useful

Haha, I was trying to say at least he is still motivated. :P
But fair enough.

It's not their skills I will miss, but their personalities and the lost development. I don't really get the same sense of endearment with these newer characters.

Game-play wise, I hope Lee ditches them and starts taking his chances alone with Clem. I don't trust them.

and two of them are injured

Yeah...that about sums it up. In my game, I still need to shed Kenny and Ben too. Damn...I'm going to need some solid reinforcements asap or it's game over.

This. exactly. I feel like I am repeating myself on these forums but I think Kenny is MUCH MORE usefull now than he was before. As sad and tragic as his life has come to, his whole focus now is to stay alive and benefit the group. We even see it when he is helping omid learn the train controls unless "something happens to me."

As for Ben, I think he also very usefull. After betraying the group (in which only Lee knows- keep that in mind) I feel like he will be a man of his word and "step up". I think he has the potential to be a badass. I mean if you think I am wrong go back to where he confesses to lee and look at how much he is willing to do anything for forgiveness.

Chuck seems to be smart and carefree, which could potentially be of great use because 1) we know he wont be starting any fights and 2) he has knowledge of the zombies obviously.

Omid and Christa, I dont know yet....no one knows yet. they seem pretty trustworthy and able bodied (given omid broke his leg but still) so we'll have to see.

I meant to tag some of this on to my original statement, too. xD
I very much believe Kenny will be way more likable from this point on.
