Thank you! I just didn't want to waste my time looking for them in areas they wont be. (...because sitting around playing an app on my phone isn't a waste of time or anything....)
Honestly I wouldn't even waste beer on LVL 1 Titans, I personally didn't hit any lvl1, I think it's better to save the beer for lvl2s and lvl3 Titans. Sometimes waiting is better in the long run.
