1. If your team has a medic, try to be next to him all the time. Overheal is a very important thing in TF2 (E)

2. Avoid fights you can't win try to only attack when you are 100% sure you will win

3. Using a charge to jump on someone around a corner is a good strategy

4. If you have 4 heads most likely the whole opposing team will try everything to kill you so be careful

5. Jumping and other tricks that rely on the "trimp" technique are very important and useful so if you see any ramp try to use it to turn into a black projectile that will deal -195 to the enemy

6. Knowledge is the key, analyzing what is happening on the map and what the opposing team has and what yours has is quite important so keep your eyes peeled

7. Remember that there are 3 different shields and each of them works differently, for example, a normal chargin' shield is fire resistant, so the pyro update won't bother you as much

8. Shield Bash also has its damage which in some situations can save your life and your killstreak for example Splendid Screen
is able to deal -128 health but only when you have 5 heads, If zero heads it will normally deal -85 health

9. m_filter 1 fps_max 60 or +left + right and cl_yawspeed 230 for better charge turning

10. Jump Charge Script is important make sure you have it
