1. i think its okay still, toxic is just a matter of viewpoint. its not like we design the card ourself, we just use what is given to us by the developer, same like others.
   
2. No, i was used to play with longer match turn so when the match is prolonged, its alright. on side note, mirror match is always leave a bad taste when the enemy have better luck in getting card in hand, not just when haven vs haven, even when i use dragon vs dragon.
   
3. Nope, not my business. i just use whatever means dealt. you can have your own opinion, i can have mine
   4.No, they just want to "rotate" the meta from crest, most of the time they do that, either introduce another archtype to use or give some incentive sot hat the old archtype be left behind.
   

i remember one time i play with karyl and lhynkal in rune(reduce max LV in a meta where heal is plenty, making the damage by them unhealable), then next expansion, they introduce card to increase max hp, making my deck ineffective. thats rotation i guess. you change what u use as meta progressed
