it seems you TOTALLY missunderstood my answer lol
replace my 5mins (i meant the time solely for running, and even this is sometimes too less) with your 20mins and i say exactly the same as you. i HAVE exactly the same oppinion like you
so you must have totally missunderstood me. or i do not get it.
i play this game since may 2005 without any interruption ever (yes, i have that bronze orc statue from blizz) and i have raided a lot in vanilla. so i remember myself very well to the corpse runs through the dessert, down the fat chain, into MC until you finaaaaally reached i.e. majordomus.
some ppl here, that maybe started with MoP, will have a hard wakeup when they start jumping into classic
and no, i would not advise to play some special snowflake hybrid spec in classic
you CAN play druid if you are ok to heal in 90% of all raid cases. you CAN play pally, if you are ok to sit a full raid evening to be called for 5mins. you CAN play shaman if you are ok to be a cleanse bot. but otherwise... i would play 1 of 5-7 specific specs
