I also sympathise with the desire to boost the BGWH. However, giving them 1+ initiative with the current Farsight rule is OTT because it means an undamaged BGWH will retain on a 1+. This is significantly better than any other unit in the whole of E:A (with the notable exception of the Warlock titan). Even titans and Aspects only retain on a 2+, while the majority of Eldar formations need a 3+ which balances out the benefit of the Eldar double retain. Unfortunately, the current approach to this conundrum does not completely resolve this particular issue.
Removing Farsight from the BGWH would help as it would return the balance of the game allowing some chance for a retain to fail. Unfortunately that also removes the iconic Eldar double retain. What we need is some form of hybrid solution that gives a 1+ initiative without a 1+ retain, whilst retaining Farsight to enable the Eldar triple retain.
Spitballing here, as this may not be palatable to others, but we could consider amending the Eldar Farsight rule. Call it something like "the Ulthwe Farsight rule" and reword it to remove the -1 for retaining. For example:-
Quote:
Eldar Farseers are able to partially unravel the threads of time, allowing them to foresee events that may affect his army, and act to counter them.
Once per turn the Ulthwe player may attempt to retain the initiative twice in a row (i.e. the Ulthwe player can retain the initiative and take another action after having successfully retained the initiative once already). Any Ulthwe formation may be chosen, including those that do not include a unit with Farsight, but at least one unit with Farsight must still be in play and on the battlefield. The formation must still pass an initiative test in order to carry out the action. Once the action has been taken the initiative returns to the opposing player.
Note, this approach would also make the Warlock slightly less powerfull as it would remove the auto retain from that monster, though I am sure that would not displease everyone . . . .
