There is actually a big problem with 5e rules where it is way to easy to break a spell that requires concentration. There is no concentration skill nor is feats as frequent as they used to be in 3.5 or pathfinder. Which both would buff the ability to stay focused on the spell while in battle. With the lackluster focus on concentration in the rules, those spells become more of a waste of time and unnecessary feature.
There is actually a feat that gives advantage on saving throws to maintain concentration called War Caster. I'd say it should be implemented on a full release, but at this point I don't know if some feats will be left out on purpose.
