time for some Linguistic commentary. gonna play a bit of Devils advocate here.
Firstly, yes - BB is bring in new rules which will hopefully make it less viable fo the tanking and the short term hiring and the selling and the renting and this tactic in general. I think BB are doing good things with regards to this - they got rid of the 5th placed financial advantage thingy, and are bringing in incentives for people to finish in the finals etc.
so these are all good things.
And hopefully this will make the game more realistic, as Akuma says rightly so, no real life situation exists where people can rent Dwight Howard for a week. so hopefully these improvements will make the game more realistic.
Secondly - Just an observation of mine - of all the teams that ive seen tank/buy up big towards end of season, rent a big, etc, ie: Do all these short term gain things - I've never seen one succeed long term. This is why I don't do this tactic. There are multiple teams in this league that have the capacity to do it, and have had that capacity to do it yet choose not to. why? Probably because there is something tactically long term wrong with it. I dont mean ethically wrong, i mean, Buzzerbeaterally(new word!)
Thirdly - I was watching a terrible terrible Aliens movie the other day, can't remember what it was, must've been Alien v Predator - "The enemy of my enemy is my friend"
If i remember correctly, it didnt work out to well for them.
