Best Upgrade Order for Deadpool

The first upgrade should be for Deadpool's 'E' ability. This upgrade grants Deadpool a 40% damage reduction and provides allies within the circle a 20% damage reduction, making it crucial for tanking and team survivability.

The next upgrade should be the sword dash. This improves mobility, allowing for more dashes and easier ultimate upgrades, which is essential for positioning and engaging enemies.

The third upgrade focuses on the ultimate ability. Before upgrading, it provides shields and healing over time. After completing its challenge, the ultimate doubles healing to 100 heals per second and grants additional shields upon activation. Furthermore, sword attacks will then provide shields to Deadpool and allies upon hit.

After the initial core upgrades, the choice between upgrading guns or swords depends on playstyle and team composition. Swords offer increased damage, attack speed, and critical hit chances for aggressive, brawl, or dive playstyles. Guns allow for three-taps instead of four, increasing DPS, and provide an additional projectile ability.

The gun upgrade is not as urgent because Deadpool's base gun ability is already effective. While the upgrade improves it, it's not as critical as the early defensive and utility upgrades for a tank Deadpool.
