No concerns huh? I guess wizards dont have to worry about being killed by a dragon's breath weapon, or knocked down and conventionally stabbed? An Ancient Red Dragon's breath weapon has a DC that a wizard probably cannot match without feats or ASIs, and deals more D6s of damage than they get hit dice. Statistically speaking, a failed save is death for most wizards who dont specifically build to survive that.
Death is the best status effect, and that cuts both ways.
Also, if youre getting 2 ASIs, youre only level 10 at best. NOTHING pre-10 is putting out such a high DC that you genuinely cannot match it.
