Level 2 Lazer Blazer takes longer to heal

I noticed nobody pointed this out, although i'm sure it's easy to overlook.

Anywho, as a support class my strategy tends to stay in the base and heal the turrets as they come under fire. However, the one thing I noticed (as the title says) was that the level 2 Lazer Blazers take much longer to heal than the level 3 version. I'm not sure if this is because it was intentional or never noticed, but it seems like an issue that you might wanna have looked at, albeit a minor one.
