Nenin is kinda right - if you get one of the bad solo q healers you will die most likely thats true; however the main problem is mages using their defensive cds at the randomest times, not eating enkindle with manaward, walling before they even engage some1 and stuff like that

Mage is great at avoiding dmg in many ways - if you are facetanking blame yourself 1st and foremost, not the team

Most importantly - i would strongly advise against speccing / stacking VIT; your dmg will be terrible and smart teams will just straight up ignore you

An example of that is Vexx Licious if any1 has seen that mage - he has like 5800 hp, does no dmg whatsoever; every time we play vs him we just ignore him (cc chain) and kill him last. He ends up with like 2300 dmg when every1 else did 10k

Its like saying that mage in wow should stack stamina since a lot of teams try to pressure / kill the mage as a priority
