Pooling all items into one does not help without a scroll bar to veiw all item at once by scrolling. Currently their is a way to find where your current retainer is by hitting menu > retainer .... should tell you where your retainer is and which ward. I have no issue because I have both my retainers in a uldah ward and never take them out for anything. I ensure there is an item noone buys on my retainers. I agree with the pooling but if they do pool allow for scrolling and purchasing the items. Alot of current highly sought after HQ items have to be found via searching every ward and if I had to search every city this causes undue travel. I have tried going to other cities for lower price items but they seem to be overpriced because they are set at a price and undercutted in uldah within mins.
