Spell timers linkingFollow

After the "big update" I noticed that a lot of my spells link together now. What I mean is, when I cast one spell, the other spells like it (in the same line) also suffer the first one's recast time. I usually can cast two heals back to back, but now I can only cast one and then wait for the recast time to cast any of my others. Was this an intentional change? Does anyone know? This is extremely lame in my opinion. I sure hope this is just a bug.

It only really hurts during the first few levels. After a while you get spells that are not in the same line but do the same job.
