Brand can slow for multiple seconds with rylais and his passive
shouldn't allow brand to be able to perma slow you. Especially since most of his abilties are AOE and already deal a ton of damage.
I don't think it's healthy that brand can abuse this item to the point that he can slow people for 4+ seconds and catch anyone who tries to run away or negates peoples ability to dodge his spells because they can't move fast enough anymore.
Spells should slow the target for 20% for 1 second (that's the description) it shouldn't reaply every tick of DOT because that's not what it says it does.
If someone who bought rylais hits a spell it should slow you for 1 second, DOT or not (especially when DOT can last for seconds).
against him since it gives slow immunity or removes cc from an ally
and
. This is probably even worse than the example you mentioned, OP.
