Picking your summoner's abilities

Normally I start with blood boil, however, it can be beneficial to start ice blast if you have an adc that won't be able to harass as well as the enemy adc, or if you are playing more defensive. I generally level blood boil and ice blast equally, but it is ok to level ice blast before blood boil for the same reasons as picking it first. Finally, delay consume as long as possible, since it doesn't help your adc and it doesn't harass the enemy team. In fact, it actually steals cs from your adc and pushes the lane! Eventually you will need it for sustain though, so get it after you have run out of pots and are around 40% HP (if you try to delay it until level 7 make sure you have at least 80% hp at level 5 and play defensively until level 7).
