Lekr0 is IGL and is the best one they've had for quite some time.
Not having a dedicated AWP:er might be unorthodox but they got 4 capable AWP:ers in Dennis, F0rest, Lekr0 and REZ. So instead of having the AWP:er change position in CT-side all the time they now just need to learn positions and how to play them depending on what weapon you got. It creates an element of surprise which is difficult to handle for the oponent.
Take Liquid for instance. If you get kille by an AWP from someone other than Nitr0 you know they do a double AWP setup, but against NIP you have no idea until you found both AWPs.
Plus; Draken isn't particulary good and he is toxic as hell, while Lekr0 is a great teammate.
Just check the results for NiP and Fnatic after the "trade" was done. NiP rose through the rankings while Fnatic dropped until they got rid of Draken.
The problem in NiP is not the two things you bring up, but that they have players ageing and is on the end of their career. GTR is an amazing player but he is not nearly as good as he used to be and there are many youngsters that can take his spot. He is there because he is one of two "mr NiP".
If they wanted a dedicated AWP:er they got Dennis who is better than Draken or they can being in nawwk who is one of the best AWPers in the Swedish scene right now.
