You can't reach level 26 without chests.

When playing for speed, it's sometimes impossible to reach the maximum level. But why try if you can easily catch up in the next mission? After all, the final level of the hero doesn't affect anything, but the speed of completion does affect the score in the final table. Essentially, it doesn't matter if your hero is level 25 or 26. The difference may only be in the availability of very useful skills. It makes sense to take experience from chests if you are sure that you will get some valuable skill (like Battle Doctrine, for example) at a certain level. For example, if the exit from the spawn is blocked by a strong squad, and you need to break through early...
