With the new current roster of Sentinels(N4RRATE included), Bang would be replacing the role of Tenz as a smoke rather than a flex but the question is whether he will do great in the team.
Stat wise- Bang has a good omen but in an area where he is very very good whereas his Viper is kinda ok but not good. He can be very incosistent from time to time
synergy wise- Considering that in a month they start to play with each other, it seems decent enough time to build good synergy together, but not as good as the past years of experience he had with 100T.
Role Wise-Since he is more of a Smoke player rather than a Flex like Tenz was, It doesn't seem he has to change roles and just stay as smoke for the rest of tournaments which is good since thats what he as been doing on 100T as well.
Mechanical Wise- Tenz high diffs Bang Mechanically since alot of the kills that bang has comes from raw aim dueling.
8/10, His new change will either bring a better him considering the different approach of the team or a worse him considering the new team. He has a great potential to do great things on Sen rather than on 100T when given a competent duelist.
edit:I just came back recently and turns out I made a mistake in the mechanical wise and said that Bang high diffs tenz. Not to sound like a massive Tenz glazer but Tenz is most definitely better than Bang mechanic wise
