The batsman should adjust to the team, and not the other way 'round. There is no excuse for not controlling strike if you're sent in to bat at #5. It's no good for your team - not a matter of "taking the blame" but simply a practical issue of scoring runs. Tailenders are hapless the world over - you know this for a fact and adjust your game accordingly. They shouldn't take the blame for the fact that a batsman is unable to do his job of not exposing them to the bowlers.
How effective can be a batsman if he himself is not sure that he is not going to last the over?
And your notion of tailenders hopeless worldwide is a statement which is made totally random. Consider how many tailenders are making 50s and even 100s : Vettori, Taylor, Kumble have all made 100s and Harbhajan, Steyn, Zaheer, Johnson, etc have made 50s. So it is an eroding perception that tailenders cannot take care of themselves nowadays.
So what should the No.6 batsman do? Realisically two things:
1. Never miss a scoring opportunity.
2. Put faith in your partner, because that is the base of any partnerships.
Laxman did exactly those two. Imagine if he did not place enough faith on his partner, and hogged the strike all by himself, taking only singles off the last ball, he survives like that for say 10 overs, and add what? 10 runs. The other scenario would be taking singles when they are on offer, say twice in an over, and assuming tailender is able to put some bat to ball, he scores another run every two overs. The result if they bat together would be 25 runs every 10 overs.
So it is a big myth that "protection" of tailenders is a job every No.6 batsman has to perform. A certain Steven Waugh made tons throwing out that myth out of the window. Unless the tailender is Munaf Patel or Chris Martin, two glorious exceptions than rule, I don't think batsmen be least bothered not to rotate strike.
