it's not as shortcoming of the warlock class it's the shortcoming of concentration spell. If you don't believe me you can always try the same two spells on other class you just need a feat. I guess that's hard for you to see? Like i said Magice missle needs concetration to add to deliberately harsh restriction that lead to harsh choices...Those Improve the game according to some.
Noone is failing to understand that there are frustrations with being limited to a single concentration spell, only pointing out that it was introduced as part of the D&D 5e ruleset that underpins the game for a reason. Getting rid of concentration entirely for some or all spells is something that could have a cascading impact that takes us further and further from those rules and 5e spells, that might need durations added or changed and alternative ways of breaking them introduced, plus ways of handling buff-stacking that as Tuco says was the prompt for introducing the concentration restriction in the first place.
Personally, I’m in favour of sticking to 5e as closely as possible even where it’s not perfect, particularly in a game that still has a stated ambition to represent the 5e ruleset, no matter what compromises have already been made. That said, I would be prepared to consider arguments for specific spells that could be changed to duration- rather than concentration- based. But as Tuco said, the use of concentration in the game is way off topic for this thread about magic missile, so that debate should probably be elsewhere.
