Use guns with high spread in TS like the 30k pumpgun at aimpoint island to reach spots without having to rush.
If you rush, then use guns with low freeze, so that you're be able to dodge bullets or to run. If you wanna hold mid then use a gun, which can spam like AA12.
Avoid to rush at the beginning since there are the most players who can damage you, dont rush If youre under 15 Hp, just my suggestion.
