event packs are better deals so its obvious that if you spend from time to time on it you get better things than one time purchase of diamonds
support lvl 10-14 dmg difference is 10% and xp 20% with event points milestone you get 3% dmg 1% xp every 50 ep so you can easy outnumber support lvl bonus with less money but it takes time
also you forgot one thing you can get half amount of ep for free so dont compare it support lvl to event packs
